What is a switched capacitor circuit?

Switched capacitor circuits are not new. James Clerk Maxwell used switches and a capacitor to measure the equivalent resistance of a galvanometer in the 1860’s. Figure 9.1-1 (a.) Parallel switched capacitor equivalent resistor. (b.) Continuous time resistor of value R.

What is the feedback factor of a switched capacitor?

Chapter 12. Introduction to Switched-Capacitor Circuits 427 the feedback factor equals C2 = (1 + in 2)in the former and H in the latter. For example, if C in is negligible, the unity-gain buffer’s gain error is half that of the noninverting ampliﬁer.

What is the phase shift of a switched capacitor inverting amplifier?

The phase shift of the switched capacitor inverting amplifier has an excess linear phase delay. When the frequency is equal to 0.5f c, this delay is 90°. One must be careful when using switched capacitor circuits in a feedback loop because of the excess phase delay.

Can a switched capacitor circuit be used in a feedback loop?

One must be careful when using switched capacitor circuits in a feedback loop because of the excess phase delay. Transresistance circuits are two-port networks where the voltage across one port controls the current flowing between the ports. Typically, one of the ports is at zero potential (virtual ground).

Why do we use switched capacitor circuits?
