Abstract:
In this paper, a useful procedure to design folded cascode (FC) and recycling folded cascode (RFC) OTAs is presented. The proposed procedure is based on a simplified equation of input voltage noise in strong and weak inversion regions. The presented method considerably decreases the input referred noise of amplifiers in weak, moderate and strong inversion. The proposed amplifiers were simulated in 0.18µm CMOS technology, achieving 36% and 25% reduction of input voltage noise @ 1Hz in strong and weak inversion, respectively, compared to the conventional FC, without increasing power consum

Abstract:
By using Gm-C compensation (GCC) technique, a two-stage recycling folded cascode (FC) operational transconductance amplifier (OTA) is designed. The proposed configuration consists of recycling structure, positive feedback and feed-forward compensation path. In comparison with the typical folded cascode CMOS Miller amplifier, this design has higher DC gain, unity-gain frequency (UGF), slew rate and common mode rejection ratio (CMRR). The presented OTA is simulated in 0.18-μm CMOS technology and the simulation results confirm the theoretical analyses. Finally, the proposed amplifier has a 111 dB

Abstract:
We show how the MOST threshold voltage can be reduced simply by forcing a constant current through the transistor bulk terminal. We characterize two versions of the resulting current driven bulk device by simulations, and conclude that this is a good method for improving circuit performance when the voltage supply is very low. Finally we show how the technique can be used to implement a 1 V folded cascode OTA with compatible input and output voltage ranges.

Abstract:
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.

Abstract:
In this paper, a single-stage multi-path operational transconductance amplifier (OTA) with fast-settling response for high performance applications is designed. The produced amplifier uses current-shunt technique, double recycling structure, cross-coupled positive feedback configuration and all idle devices in the signal path to enhance transconductance of the conventional folded cascode (FC) amplifier. These transconductance boosting techniques lead to higher DC gain, gain bandwidth (GBW), slew rate and lower settling time compared to the previous FC structures while phase margin is degraded.

Abstract:
Testability is crucial in today’s complex industrial system on chips (SoCs), where sensitive on-chip analog voltages need to be measured. In such cases, an operational amplifier (opamp) is required to sufficiently buffer the signals before they can drive the chip pad and probe parasitics. A single-stage opamp offers an attractive choice since it is power efficient and eliminates the need for frequency compensation. However, it has to satisfy demanding specifications on its stability, input common mode range, output swing, settling time, closed-loop gain and offset voltage. In this work, the se

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.
