In this paper, we describe a new method to deal with analog signal in time domain. The method converts voltage signal to time-interleaved phase modulation signal of clock edge. After being amplified by a new time amplifier(TA), phases of the signal a

This paper presents a low distortion 3rd-order continuous-time delta-sigma modulator for a worldwide digital TV-receiver whose peak SNDR is 69.8dB and SNR is 70.2dB under 1V power supply. To enhance SNDR performance, the mechanisms to occur harmonic

Conventional continuous-time (CT) delta-sigma (??) analog-to-digital converters (ADCs) consume large amount of power in operational amplifiers of a loop-filter. We propose a new loop-filter with single-opamp resonator, ringing-relaxation filter and p
