Abstract

Phase compensation circuit is an important building block for many analog circuits. Some applications such as DC-DC converters need compensation circuits with external large capacitances. In order to integrate the phase compensation circuit, the capacitance should be reduced. The time-mode Miller compensation circuit is considered as one of the good candidates for this purpose. In conventional method, a compensation circuit with a zero on its transfer function needs two Operational Transconductance Amplifiers (OTA). This paper proposes an implementation of compensation circuit using time-mode capacitance scaling with one OTA combined with a continuous time current-mode capacitance multiplier. The proposed circuit is verified using Spectre simulation.
