Title:
CIRCUIT WITH INDUCING CHARACTERISTIC
Document Type and Number:
Japanese Patent JPS5871711
Kind Code:
A
Abstract:
A circuit having an inductive characteristic for the realization of filters in integrated circuits is constructed solely from switched capacitors and an operational amplifier. The circuit is provided between a first and a second terminal with a first capacitor in series with at least one switch. The switch is capable either of connecting the first capacitor between said two terminals or of isolating said capacitor from the first terminal. The circuit further comprises an operational amplifier having a feedback path between its output and its input via a second capacitor, and additional switches for transferring charges from the input of the circuit to the first capacitor and then from the first capacitor to the second capacitor, then again from the second capacitor to the first capacitor. Under these conditions, the circuit exhibits the characteristics of an inductance.
