—This paper presents a high-level synthesis tool for 61 modulators (61 s) that combines an accurate SIMULINK-based time-domain behavioral simulator with a statistical optimization core. Three different circuit techniques for the modulator implementation are considered: switched-capacitor, switched-current and continuous-time. The behavioral models of these(More)
—This paper presents novel architectures of multirate hybrid cascade continuous-time/discrete-time !" modulators that take advantage of the potentially faster operation of the continuous-time part of the circuit, while keep a reduced sampling operation of the back-end discrete-time stages. Compared to conventional multirate !" modulators, the proposed(More)
