Abstract
High-speed front-end amplifiers and CDR circuits
play critical roles in broadband data receivers as the former needs
to perform amplification at high data rate and the latter has to re-
time the data with the extracted low-jitter clock. In this paper, the
design and experimental results of 40 Gb/s transimpedance-AGC
amplifier and CDR circuit are described. The transimpedance am-
plifier incorporates reversed triple-resonance networks (RTRNs)
and negative feedback in a common-gate configuration. A mat
