- Abstract : Over the last couple decades or so, there has been a
growing interest in dynamic amplifiers. Ring amplifier is one such type
which maintains closed loop dynamics and accuracy. Ringamp was first introduced
at ISSCC in 2012. Significant advancements have been made since that time. A
number of implementations have demonstrated unprecedented efficiency in residue
amplification of cascaded ADCs. Publications on ringamps are now appearing from
various authors from around the world. This presentation will start with
initial ringamp basics and build from there to provide a brief history of
various/notable implementation examples. Naturally a greater focus will be
given to examples from my own group, which includes pseudo-pseudo-differential
delta-sigma modulator and predictive level-shift buffering of input signal in a
two-step ADC.
