CDMA channel selection requires sharp as well as wide-band Filtering. SAW Filters which have been used for this purpose are only available in IF range. In direct conversion receivers this has to be done at low frequencies. Switched Capacitor technique has been employed to design a low power, highly selective low-pass channel select Filter for CDMA wireless receivers. The topology which has been chosen ensures the low sensitivity of the Filter response. The circuit has been designed in a mixed-mode 0. 18u CMOS technology working with a single supply of 1. 8 V while its current consumption is less than 10 mA.
