A monolithic c.c.d. filter for p.c.m. codec was fabricated employing both a minimum-phase design with a substantially reduced number of taps and almost perfect elimination of excess capacitances. Results, such as negligible degradation in frequency responses, considerable reduction of common-mode signal, low filter noise (−78 dBm) and wide dynamic range (84 dB) were successfully obtained.
