摘要: A complete monolithic state variable filter is described which has been fabricated with bipolar technology. Two-quadrant multipliers are used in a novel fashion to achieve integration time constant large enough for audio purposes. Voltage control of frequency response from 20 Hz above kHz achieved without sacrifice accuracy (notch depth >50 dB, low-pass and bandpass responses accurate better than 0.1 dB), dynamic range (>90 power supply rejection (PSRR>40 dB) or drift (<200 ppm//spl deg/C). The design shown be generally useful the self-contained filters.
