This article proposed a deep-pipelined analog-to-digital converter (ADC) that utilizes an input-split fully differential ring amplifier (ringamp, RAMP). The implemented ringamp is optimized for speed, achieving higher nondominant pole frequency, and exhibits excellent adaptability in low-voltage, deep-nanoscale advanced CMOS processes. To minimize nonoverlap time, nonoverlapping clock generator employed, generating two-phase clocks with near 50% duty cycles sampling amplification the...
This paper proposed a pipelined analog-to-digital converter (ADC) that utilizes high-linearity input buffer and two-step input-split fully differential ring amplifier (ringamp). The implemented based on gain-boost cascode current source, is optimized for linearity over wider frequency range by suppressing fluctuations in tail current. To save power consumption without compromising common-mode power-supply rejection, employed as the residue amplifier. Additionally, correlation-based...
This work presents a single-channel, fully dynamic SAR-assisted pipelined analog-to-digital converter (ADC) with wide input range. The ADC employs resistance assisted two-stage amplifier based on gm-unit to achieve outstanding residue amplification efficiency and settled-time. It has small variation in parasitic capacitance high linearity leverages bias compensation circuit reduce the gain temperature drift. Moreover, an improved bootstrap switch optimization, is adopted stable sampling over...
