Abstract
A method described in this paper is to design a mixed signal integrator, where the signal integrations performed are analog, but the results have both analog and digital signals. The function of an electronic integrator is to integrate any arbitrary analog signal exactly without saturation. The mixed signal integrator collects the signal integral further than the supply rails without operational amplifiers saturation and the operational amplifier design has been carried out using cadence tools based on 180nm technology and the simulation results are verified. The mixed signal integrator is consisting of an analog integrator (operational amplifier with feedback capacitor) with comparators, counter registers, and the logic. As a building block, the two Stage CMOS operational amplifier is designed and trade-off curves have been computed between all characteristics such as Gain, ICMRR, CMRR, Slew Rate etc. , and the mixed signal integrator is promising that the strengths of analog are often weaknesses of digital, and vice versa. .
