A custom FM stereo decoder IC which uses switched-capacitor and linear filters, linear MOS and bipolar circuitry, and digital MOS circuitry to eliminate the requirements for accurate external components and external adjustments is described. The IC includes a combined analog/digital VCO and PLL, a switched-capacitor sine-wave multiplier, and a switched-capacitor pilot detector and cancellation stage. An output
