AN64475 - PSoC®1 - Optimizing Cascaded Switched Capacitor Filters

AN64475 demonstrates how PSoC® 1 switched capacitor band pass filters (BPF2, BPF4) and elliptical low pass filters (ELPF2 and ELPF4) can be combined to provide excellent near out-of-band rejection for communications applications. The included project demonstrates a filter system tuned to the requirements of a 60 kHz Binary phase shift keyed (BPSK) modem receiver. The design technique can be extended to other requirements using the filter design wizards in the user modules in PSoC Designer.
