Abstract:
Abstract This paper presents a high-gain, high-drive operational amplifier based on the 0.18 μm technology. The first stage employs a current-reuse common-source common-gate structure to enhance gain, while the second stage utilizes a transconductance-enhanced push-pull output stage. This design achieves high-drive performance while retaining a high gain. Simulation using Cadence software demonstrates that, under a 5 V power supply voltage, the amplifier exhibits a low-frequency gain of 120 dB, with output sink and source current capabilities reaching 17.7 mA and 2.53 mA, respectively.

Abstract:
A low-power wideband mixer is designed and implemented in 0.13 µm standard CMOS technology based on resistive feedback current-reuse (RFCR) configuration for the application of cognitive radio receiver. The proposed RFCR architecture incorporates an inductive peaking technique to compensate for gain roll-off at high frequency while enhancing the bandwidth. A complementary current-reuse technique is used between transconductance and IF stages to boost the conversion gain without additional power consumption by reusing the DC bias current of the LO stage.

This paper presents a low-power low-noise instrumentation amplifier (IA) for bio-potential recording. The proposed IA is based on a novel Gm-RSC structure, whose gain is determined by the transconductance (Gm) and the equivalent resistance ([Formula: see text]) of the switched-capacitor (SC) load. The transconductance amplifier stage is based on the current-reuse telescope topology to achieve low noise at low-power dissipation. A resistor-controlled oscillator is designed to generate desirable operational frequency for SC load and to continuously tune the mid-band gain of the IA for different

Abstract:
An idea for a digital optical transconductance amplifier is presented in this chapter. The amplifier that is being suggested here enables you to rate each noise modification for each channel while reducing overall power consumption and satisfying all application criteria. Power upgrades for current and power sources, multiplied by various supply voltages, will be used in the low-voltage current-reuse re-topology. High efficiency is a goal of the power management circuit, which offers a range of supply voltages. A low-voltage amplifier is utilized in a typical 0.18-m CMOS and is installed by testing following its power cycle. Both noise efficiency and power efficiency are essential for the amplifier core. Each data point corresponds to a voltage range and is called into the digital architecture concerning the rising edge of the 40MHz clock (sampling clock).

Abstract:
The main design goals of an LNA are to achieve low noise figure, high gain, good linearity and good matching and reverse isolation. The choice of the LNA topology is therefore very important to suit the design application. Five LNA topologies were studied, analyzed and compared in this chapter. The topologies are the Simultaneous Noise and Input Matching (SNIM), Power-constrained Simultaneous Noise and Input Matching (PCSNIM), Current-reuse (CR) and Folded-cascode (FC) LNAs. The last topology is the PCSNIM with buffer. The circuits are analyzed in detail in terms of their functionality and compared based on the LNAs typical performance metrics. From the analysis, the PCSNIM technique can improve matching and noise performance of the inductively degenerated cascode. The current-reuse is found to consume less current but maintaining the circuit’s transconductance to achieve the desirable gain. The folded-cascode operates at lower voltage and hence is suitable for low-powered designs. Consequently, it is also resulting in the lowest noise-figure amongst the other designs.
