Abstract

Applications like counter ADC demanded accurate ramp signal with low power dissipation. This paper presents a novel approach of low power differential ramp generator with negative feedback for the compensation of the variations in process, voltage, and temperature (PVT). The derived equations of the proposed ramp generator circuit show that PVT compensation is enhanced significantly. Additionally, the circuit design and simulations were done in TSMC 0.18-μm CMOS technology. The Monte Carlo simulation results and corner analysis show that the linearity of the ramp signal is about 9-bit while power dissipation of the circuit is about 2.61μW.
