全体主题 > Analog Circuits

The paper proposes an 8-bit, 8-GS/s time domain analog-to-digital converter (TD-ADC) with equivalent time sampling technology. The prototype was fabricated in 65 nm CMOS technology. This ADC has a high area efficiency. The core area of the chip is only 320μm×300μm. The measured SFDR and SNDR are over 43.0 dB and 57.6 dB with a Nyquist input.
