N2 - This paper presents a novel technique to design a programmable bandwidth single-ended output CMOS operational amplifier using a serial digital interface. The circuit topology enables the programming of the value of a negative Miller capacitance around first amplification stage and programming of the value of a Miller capacitance around the second amplification stage. Therefore, a controllable frequency response op-Amp is created that can be digitally controlled from a host digital processor. The design is based on a rail-To-rail output CMOS operational amplifier architecture where the first stage of the op-Amp consists of differential input and folded cascode circuits, and the second stage is a class AB amplifier. The design has been designed using a 0.35 μm CMOS technology, its operation simulated using the Cadence Spectre simulator and operates on a +3.3V power supply.
