単一演算増幅器型2相高次スイッチトキャパシタ低域通過フィルタの構成

抄録

This paper proposes parasitic compensated 2-phase 3rd and 5th-order switched capacitor low-pass filters using single operational amplifier. The effect of parasitic capacitance can be theoretically removed under the assumption that ratio of capacitance and parasitic capacitance is constant. Simulation results show good agreement with the theory.
