Programmable Capacitance Multiplier with DAC

Capacitance multiplier simulate high capacitance capacitor for analog signal signal processing. By using DAC (Digital-to-Analog Converter), we can simulate variable capacitance with very wide range, which can be used in digitally controlled analog processor (programmable filters for example). The following circuit shows a DAC0830 connected as a capacitance multiplier. This circuit is a DAC controlled amplifier (used capacitance multiplication) to […]
