Abstract :
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 S/N ratio greater than 80 dB and output distortion less than 0.1% have been achieved. The part is 26000 mils2 and is implemented in a 3 μm n-well CMOS process containing poly-to-poly capacitors, n-p-n´s, and ion-implanted poly resistors
