Abstract:
Design and simulation of 7 GHz CMOS wideband amplifier(CMOSWA) using a modified cascode circuit realized in 90-nm CMOS technology is presented here. The proposed system consists of two stages, namely a modified folded cascode and an inductively degenerated common source amplifier. The circuit is experimented with and without a feedback network. This work discusses the performance variation as a function of reactive components, and the initial stage results in 22 dB gain,2.6 GHz bandwidth, and 40GHz unity gain-bandwidth. The circuit without the feedback network exhibits 30.7dB gain,4.8GHz bandw

Abstract:
A programmable gain amplifier (PGA) is commonly used to optimize the input dynamic range of high-performance systems such as headphones and biomedical sensors. But PGA is rather sensitive to electromagnetic interference (EMI), which limits the precision of these systems. Many capacitor-less low-dropout regulator (LDO) schemes with high power supply rejection have been proposed to act as the independent power supply for PGA, which consumes additional power and area. This paper proposed a PGA with a high power supply rejection ratio (PSRR) and low power consumption, which serves as the analog fr

Abstract:
This paper presents a low-voltage low-power chopper-stabilized differential difference amplifier (DDA) realized using 40 nm CMOS technology. Operating with a supply voltage of 0.5 V, a three-stage DDA has been employed to achieve an open-loop gain of 89 dB, while consuming just 0.74 μW of power. The proposed DDA incorporates feed-forward frequency compensation and a Type II compensator to achieve pole-zero cancellation and damping factor control. The DDA has a unity-gain bandwidth (UGB) of 170 kHz, a phase margin (PM) of 63.98°, and a common-mode rejection ratio (CMRR) of up to 100 dB. This ci

Abstract:
Constant transconductance (Gm) biasing circuits, as the name suggests, generate a bias current that ensures that the Gm of a MOS transistor remains constant. The Gm of a MOS transistor is a very important parameter as various other parameters of a circuit such as the gain, UGB (Unity Gain Bandwidth, poles, and zeros are strongly dependent upon it. Every analog circuit in a chip is subjected to varying PVT (Process, Voltage, and Temperature) conditions. This leads to a varying Gm of the devices, and hence the parameters such as the gain and UGB also tend to vary. Hence, constant Gm biasing is c

In this paper, a fast-transient-response NMOS low-dropout regulator (LDO) with a wide load-capacitance range was presented to provide a V/2 read bias for cross-point memory. To utilize the large dropout voltage in the V/2 bias scheme, a fast loop consisting of NMOS and flipped voltage amplifier (FVA) topology was adopted with a fast transient response. This design is suitable to provide a V/2 read bias with 3.3 V input voltage and 1.65 V output voltage for different cross-point memories.

This paper presents a high unity gain bandwidth fully differential folded-cascode operational amplifier using gain-boosted technique. The amplifier is designed in TSMC 0.18μm 1P6M CMOS technology. The unity-gain bandwidth (GBW) and poles of the gain-boosting amplifiers were carefully designed to improve the stability. The implemented design provides a direct current (DC) gain of around 93 dB with a unity gain frequency of 1.8GHz. It exhibits a DC gain larger than 88dB when the output common-mode voltage between 0.6 V and 1.2V. the overall layout size is 96μm×120μm.

Amorphous oxide thin-film transistor (TFT) technology has become central in flexible and low-cost electronic applications. However, there are some limitations of the technology for circuit implementation, particularly the lack of stable and reproducible p-type oxide TFTs, limited speed due to poor semiconductor mobility and to large channel lengths when com-pared to single crystalline Si devices. These limitations demand novel circuit design techniques using only n-type TFTs to achieve high-speed circuits meeting the requirement of practical applications.

Abstract:
Sensors are electrical-mechanical elements which are the interface between environment and electrical systems. The input of sensors is characteristics of the environment for example temperature, pressure and etc. and their output is a small electric voltage or current. Their job is to convert environment characteristics to an electric voltage or current at their outputs. Since the output current or voltage is very small, it must be amplified in order to be suitable for use in electronic systems. In this chapter we completely explain the design procedure and characteristics of sensor amplifiers. The important parameters of sensor amplifiers are input and output resistance, gain, unity gain bandwidth and etc. One of the most important characteristics of amplifiers is the linearity of amplification in a way that it must have uniformity for all amplitude voltages or currents in all frequencies of the bandwidth. For this purpose, first the operational amplifier is completely discussed, then the linearity of feedback operation will be explained.

Abstract:
A distributed system based on Fuzzy sets to select the optimal sizes of Unity Gain Cells (UGCs) is introduced. A zoom technique is also introduced to search for the optimal sizes in a more refined way. The selected sizes accomplish target specifications established by linguistic variables, namely gain “closer to” unity and “large” bandwidth, which are represented by fuzzy sets. The case of study is focused on three Voltage Follower and a CFOA whose performance characteristics are evaluated by using IC technology of 0.35µm and 180µm, respectively, and the circuit simulation program SPICE. Every circuit is codified by the width and large (W/L) of every Metal-Oxide-Semiconductor Field-Effect-Transistor (MOSFET) and by its bias current source. From the population of feasible solutions computed by evolutionary algorithms, the optimal W/L sizes are selected by the proposed distributed system through the intersection of fuzzy sets.
