In this paper, a three-stage class AB operational transconductance amplifier (OTA) with large slew rate is presented. The reversed nested Miller compensation technique is used to stabilize the proposed OTA, allowing the slew rate enhancement to be achieved by using class AB input and output stages. A flipped-voltage follower cell in the first stage in combination with a switched-capacitor level shifter in the last stage are utilized to implement the class AB operation. Circuit level simulation results are provided using HSPICE and a 90 nm CMOS technology which show 306 % enhancement in the large-signal FoM with approximately the same power dissipation compared to the class A OTA. The achieved settling time with 0.02 % accuracy for the proposed class AB and conventional class A OTAs are 7.5 and 15.3 ns, respectively.

“…Another contribution of this work is to include non-linear section of step response into the proposed analysis. This section plays a key role in value of total settling time and excluding it (similar to the majority of design methodologies already proposed [2][3][4][5][6][7]) might lead to unacceptable error.…”

“…In design and optimization of switched-capacitor circuits, a precise settling-based design methodology would be especially helpful [5,7,[19][20][21][22][23]. This has been formerly authenticated by the authors in [24] in which high-speed two-stage amplifiers have been considered.…”

SUMMARYIn analog signal-processing applications, settling performance of the employed operational amplifiers (opamps) is usually of great matter. Under low-voltage environment of modern technologies where only a few transistors are allowed to be stacked, three-stage amplifiers are gaining more interest. Unfortunately, design and optimization of three-stage opamps based on settling time still suffer from lack of a comprehensive analysis of the settling behavior and closed-form relations between settling time/error and other parameters. In this paper, a thorough analysis of the settling response of three-stage nestedMiller-compensated opamps, including linear and non-linear sections, is presented. This analysis leads to a design methodology which determines the circuit requirements for desired settling time/error. Based on settling time, it allows optimizations in power consumption and area.

“…Operational amplifiers used in switched-capacitor circuits are the best example of these systems. There are several techniques proposed in the literature for the design of these circuit blocks which take in account the adjustment of the settling time within a given boundary (see, for instance, [2][3][4][5]). …”

In this paper, we propose a concept of a continuous-time filter of constant component that exhibits a very short response in the time domain if compared to the traditional time-invariant filter. The improvement of the filter dynamics was achieved as a result of the time-varying parameters which were introduced to the filter structure. Such a designed filter is then applied in a system which switches many distorted signals which should be filtered as fast as possible. The paper is of review nature and presents both a theoretical background of the proposed filter and the results of simulations.
