A New High Q Single Amplifier Switched-Capacitor Filter and Its Optimal Design

本文提出了一个新的高Q单放大器开关电容(SC)滤波器,给出了该电路最大与最小电容比最小的最优设计。同已有文献相比,本文电路的最大与最小电容比已得到大幅度地减小。

A new high Q switched-capacitor (SC) filter using a single amplifier is presented. An optimal design for minimizing capacitor spreads of the circuit is obtained. Compared with the circuits given by literature, the capacitor spreads of the proposed circuit have been significantly reduced.
