Summary: | An integrated 18th-order frequency symmetrical switched-capacitor (SC) bandpass filter is described that was realized by the use of voltage inverter switches (VISs) in the form of recharging devices. The filter was implemented in a standard CMOS technology. It was conceived for use as a `channel filter' in modulation schemes for PCM/FDM and audio/FDM conversion. Starting from a high-pass filter as reference filter, the SC filter is designed as a pseudo-N-path filter, with N=2. The application of the pseudo-N-path principle leads to a substantial saving in hardware. |
