Abstract :
The analog part of a high-resolution A/D converter has been integrated in a compatible CMOS-JFET technology. The circuit, which forms a pulse-density modulator (PDM), can be operated at sample rates up to 12 MHz and reaches a peak SNR of 84 dB over a baseband of 20 kHz. This corresponds to approximately 14-bit A/D resolution.
