Abstract :
This paper motivates the use of continuous-time delta-sigma data converters for bandwidths above 100 MHz. Lowpass and bandpass designs implemented in SiGe BiCMOS and clocked at 20-50 Gb/s are described in the context of radio applications. Next, the viability of key building blocks is investigated in 65-nm GP CMOS including measurement results of a new opamp that achieves 50 dB of gain with 10 GHz unity-gain-bandwidth.
