Abstract :
A simple series switch sizing procedure is presented taking into account very low-voltage switch operation. Under these conditions, the switch conducts not only in the linear region, but also in saturation. The procedure has been implemented in an automatic sizing tool and used to optimize separately switch sizes in a very low-voltage delta-sigma modulator. This has allowed us to minimize clock feedthrough while satisfying all settling requirements
