Abstract

This paper describes a high-performance continuous-time filter which is important in various electrical equipments. Firstly, a novel phase compensation technique for high-frequency integrators is proposed. The phase lead shift is realized by using a compensation capacitor. The ratio of the zero frequency and the pole frequency can be determined arbitrarily.<br>Secondly, an elliptic low-pass filter using differential signal input integrators is discussed. A method to realize a high-precision elliptic filter is proposed. The effectiveness of the proposed techniques is confirmed by SPICE simulation. The simulation results of the integrator show that a flexible phase compensation has been achieved. The simulation results of the filter show that the elliptic filter with cutoff frequency of 10MHz can operate at a low power supply of 2V. The power dissipation is 4.72mW for a power supply of 2V.
