    Introduction to Switched-Capacitor Circuits

    Introduction to Switched-Capacitor Circuits Our study of amplifiers in previous chapters has dealt with only cases where the input signal is continuously available and applied to the circuit and the output signal is continuously observed. Called “continuous-time” circuits, such amplifiers find wide application in audio, video, and high- The objective of this activity is to extend the switched capacitor concept beyond the single capacitor and switches circuit that can be built around the CD4007 transistor array. More complex configurations require multiple capacitors and switches. Analog switches and multiplexers such as the CD4066 and CD4053 can be used. of switched mode power supplies, these cooling times are often a minor consideration because electrolytic capacitors in the circuit usually take longer to discharge fully. The NTC thermistor will therefore be cool enough to resume operation in the event of another short-term turn-on.
