This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
Generalized predictive control (GPC) offers a method of designing digital compensators directly in the discrete-time domain. In this paper, an automatic design process based on the optimization of a few GPC parameters is presented. The application to DC-DC converters offers real benefits because of its clearly defined design process, time-domain performance criteria, simple tuning technique and guarantee...
