In this paper, a high gain structure of operational transconductance amplifier is presented. For low voltage operation with improved frequency response bulk driven quasi-floating gate MOSFET is used at the input. Further for achieving high gain the modified self cascode structure is used at the output. Compared to conventional self cascode the modified self cascode structure used provides higher transconductance which helps in significant boosting of gain of the amplifier. The modification is achieved by employing quasi-floating gate transistor which helps in scaling of the threshold which as

A low voltage, low power two-stage operational amplifier (op-amp) was proposed in this paper. A folded-cascode structure is used in the input stage of the amplifier to get high gain. Current mirrors are used in the input stage to make the transconduotance constant. A simple push-pull common source amplifier is adopted as the output stage to take the advantages of its high efficiency. The experimental results show that the unity-gain bandwidth is 12.5MHz, the low-frequency open-loop voltage gain is 100dB,the phase margin is 65°, and power dissipation is 98.8μw.

Abstract This paper comments on four works for the optimization of comparator design. Today, with the development of integrated circuits, the requirements for comparators about low power, low delay, few offset voltage, and low noise are highly desirable. Specifically, these works made progress in the conventional comparator, which comprises a preamplifier and a latch. They also solved some problems, such as decreasing power and delay. Some works employ a positive feedback cross-coupled pares to provide a larger gain in the preamplifier, use PMOS switch transistors to accelerate the definition

This article presents a power-efficient low noise amplifier (LNA) with high gain and low noise figure (NF) dedicated to satellite communications at a frequency of 435 MHz. LNAs’ gain and NF play a significant role in the designs for satellite ground terminals seeking high amplification and maintaining a high signal-to-noise ratio (SNR). The proposed design utilized the transistor (BFP840ESD) to achieve a low NF of 0.459 dB and a high-power gain of 26.149 dB.

Based on the SMIC 0.13 um CMOS technology, this paper uses a 0.8 V supply voltage to design a low-voltage, ultra-low-power, high-gain, two-stage, fully differential operational amplifier. Through the simulation analysis, when the supply voltage is 0.8 V, the design circuit meets the ultra-low power consumption and also has the characteristic of high gain. The five-tube, fully differential, and common-source amplifier circuits provide the operational amplifier with high gain and large swing.

Background: Sensing of biomedical signals is crucial for monitoring of various health conditions. These signals have a very low amplitude (in μV) and a small frequency range (<500 Hz). In the presence of various common-mode interferences, biomedical signals are difficult to detect. Instrumentation amplifiers (INAs) are usually preferred to detect these signals due to their high commonmode rejection ratio (CMRR). Gain accuracy and CMRR are two important parameters associated with any INA. This article, therefore, focuses on the improvement of the gain accuracy and CMRR of a low power INA top

AbstractIn this paper, a high-gain dual-band distributed amplifier (DBDA) based on the metamaterial transmission line (TL) is proposed. To have two separate frequency bands in the distributed amplifiers, the composite right/left-handed (CRLH) TLs are used instead of conventional TLs. Although both forward and reverse gains of the distributed amplifiers are available in this case, they suffer from their low gains. In this paper, to increase the DBDA power gain, a new circuit architecture for the CRLH TL is introduced. By using the proposed CRLH TL, a lower wave attenuation coefficient at the fo

Comparators are the essential block for planning high-speed analog and. This paper presents three inventive designs of the comparators in recent years. First, innovated by classic two-stage comparator, the comparator with a transconductance-enhanced latching stage is suitable for low-power, high-speed operation. Second, triple-latch feed-forward(TLFF) fully dynamic comparator guarantees the maximum possible gain and speed for a specific power across the entire input range. Finally, the comparator with a dynamic floating inverter maximizes efficiency by reusing the current.

The paper presents a novel 5.15[Formula: see text]GHz–5.825[Formula: see text]GHz SiGe Bi-CMOS down-conversion mixer for WLAN 802.11a receiver. The architecture used is based on Gilbert cell mixer, the combination of MOS transistors and HBT BJT transistor device characteristics. The hetero-junction bipolar transistor (HBT) topology is adopted at the transconductance stage to improve power gain and reduce noise factor, and the LO series-parallel CMOS switch topology will be applied to reduce supply voltage and dc power at the switching stage. This mixer is implemented in TSMC 0.35-[Formula: see

In this paper, a high gain low voltage low power Complementary Metal Oxide Semiconductor (CMOS) Low-noise Amplifier (LNA) using Chartered 0.18[Formula: see text][Formula: see text]m CMOS process for Ultra-wideband (UWB) receiver applications is presented. A novel multiple-feedback network constructed by the shunt feedback resistor with a transformer is adopted to realize desirable bandwidth extension and less chip area occupation in the common-source stage. All the cascaded transistors are configured by current-reuse structure and adjusted by forward body bias technique to further reduce suppl

This paper proposed a bootstrapped type high-efficient charge pump circuit based on the Dickson charge pump for high output power and pump-efficiency. By using bootstrapped technique, it can increase both of pump-efficiency and power-efficiency. The proposed bootstrapped based charge pump can avoid the threshold voltage drop and enable to generate a higher output voltage. Simulation by using HSPICE level 3 model shows that for conventional Dickson charge pump, it convert the input low DC-voltage (Vin=1.5V) up to 3.8 times of it (VOUT=5.77V), the pump efficiency was 76.93%. Our work, however, c

Purpose – The purpose of this paper is to design and realize a high gain power amplifier (PA) with low output back-off power using the InGaP/GaAs HBT process for WCDMA applications from 1.85 to 1.91 GHz. Design/methodology/approach – A three stages cascaded PA is designed which observes a high power gain. A 100 mA of quiescent current helps the PA to operate efficiently. The final stage device dimension has been selected diligently in order to deliver a high output power. The inter-stage match between the driver and main stage has been designed to provide maximum power transfer. The output mat
