Abstract

This paper introduces a design for a track and hold circuit using switched cascode current mirror in.13 μm CMOS technology. In most signal processing chips it is the analogue switching section that limits the performance of interface part. Considering this, a track and hold circuit that can be used in ADC, SI filters and other interface circuits, is proposed A second generation switched current memory cell and pseudo resistive feedback are used in the circuit. As an application, an integrator using this circuit is designed. The theoretical results are verified using spice simulator with BSIM3v3 model. A low total harmonic distortion (THD) is obtained with this circuit.
