The architecture and critical circuit design issues for high-speed serial data links operating in excess of 1 Gb/s are described. Trade-offs in power vs. performance are presented for SONET/SDH transceivers and backplane transceivers for Infiniband o

A bandpass /spl Sigma/-/spl Delta/ modulator is described in this paper that uses frequency translation inside the /spl Sigma/-/spl Delta/ modulator loop to take advantage of the attributes of both continuous-time and discrete-time circuits. A CMOS d

The effect of clock jitter on the dynamic range of discrete-time (DT) and continuous-time (CT) sigma-delta modulators is addressed. It is shown that clock jitter in DT modulators mixes with the input signal, while for CT modulators, the jitter mixes

The generalized design of Automatic Gain Control (AGC) circuits that have constant settling time is described. Each of the major components of the AGC circuit is modeled and the criteria to obtain a gain settling time independent of the absolute gain

A fifth-order CMOS continuous-time Bessel filter with a tunable 6- to 15-MHz cutoff frequency is described. This fully balanced transconductance-capacitor (G/sub m/-C) leapfrog filter achieves a dynamic range of 55 dB while dissipating 96 mW in a 5-V

A synthesis technique is described whereby network functions that are rational in s are realized with uniform distributed RC elements and active elements. In contrast to previous distributed synthesis approaches, the technique works directly in the s

Two MOS squarer circuits are presented. One implementation operates on sampled-data signals, while the second uses continuous-time operation. Both squarers achieve the square-law function with MOS transistors operating in the nonsaturation region bia
