CMOS pulse-code-modulation voice codec

A standard CMOS technology has been employed in LSI realization of a pulse-code-modulation (PCM) encoder and decoder for per-channel applications in telephony. Innovations in the design of an operational amplifier, a comparator, and precision-ratioed capacitor arrays, all in standard CMOS, are repor...

Zusammenfassung:A standard CMOS technology has been employed in LSI realization of a pulse-code-modulation (PCM) encoder and decoder for per-channel applications in telephony. Innovations in the design of an operational amplifier, a comparator, and precision-ratioed capacitor arrays, all in standard CMOS, are reported.
