Abstract

A high-accuracy pulse-based analog divider with 12-bit digital output is proposed in this letter. Moreover, a comparator-delay-free voltage-to-pulse generator (VPG) and a pulse divider (PDV) are proposed: The on-time of the VPG-generated pulses is proportional to its input voltage, and is free from comparator delay; the PDV performs the functions of a divider and an analog-to-digital converter, so the output of the proposed divider is 12-bit digital code directly. The proposed chip was fabricated using a 0.35-{{\mu }}\text{m} 2P4M 3.3-V mixed-signal polycide process. According to the measured results, the maximal error is only 1.06% and the quiescent power is only 205 \mu \text{W}.
