Abstract: This paper presents a new fully differential operational transconductance amplifier (OTA) for low-voltage and fast-settling switched-capacitor circuits in digital CMOS technology. The proposed two-stage OTA is a hybrid class A/AB that combines a folded cascode as the first stage with active current mirrors as the second stage.

A fully differential opamp suitable for very-low voltage switched-capacitor circuits in standard CMOS technologies is introduced. The proposed two stage opamp needs a simple low voltage CMFB ...

The proposed two-stage OTA is a hybrid class A/AB that combines a folded cascode as the first stage with active current mirrors as the second stage. Owing to the class AB operation in the second stage, slew ...

Then a detailed discussion on a novel approach to determine the optimum bias current of the input stage will follow. Based on the proposed approaches, a fully differential low-voltage low-power very-fast-settling opamp for use in the first stage of a 13-bit 100MS/s pipelined ADC is presented.

It describes a switched capacitor circuit which uses the parallel and alternating phase clock cycle (PHI1 and PHI2) operating two switchable operational amplifiers (A1, A1 '). In a preferred embodiment of the present invention, the two operational amplifiers can be achieved by having a common input stage and two switchable output operation on a single two (Voutl and Vout2) of the amplifier.

A switched capacitor circuit is described that uses two switchable operational amplifiers (A1, A1') that operate in parallel and in alternate clock phases (phi1 and phi2). In a preferred embodiment of the invention, the two operational amplifiers may be implemented by a single two stage operational amplifier having a common input stage and two switchable output pairs (Vout 1 and Vout 2).
