Switched Capacitor Resistor. 5 2 2 switched capacitor resistors one important class of cmos analog integrated circuits are switched capacitor sc circuits where high precision resistors with large resistance values are implemented by switches and capacitors 28. The most simple switched capacitor circuit is shown in figure 1 the switched capacitor resistor.
It consists of one capacitor c 1 and two switches s 1 and s 2 which connect the capacitor alternately to the input vin and the output vout. Switching the capacitor moves a charge proportional to the voltage difference. Since these components are ideal the model of them will not have a power dissipation real world will have parasitic impedances that will dissipate power.
Switched capacitor resistor the simplest switched capacitor sc circuit is the switched capacitor resistor made of one capacitor c and two switches s 1 and s 2 which connect the capacitor with a given frequency alternately to the input and output of the sc.
The resistor achieves the same function only in a continuous manner. It consists of one capacitor c 1 and two switches s 1 and s 2 which connect the capacitor alternately to the input vin and the output vout. Both create the same flow of water on average. Switching the capacitor moves a charge proportional to the voltage difference.
