  • A novel design of contious-time filter for direct conversion receiver applications is proposed. The filter supports different modes including GSM, WCDMA. A 5th chebyshev filter is realized in a gm-C filter topology. The filter circuit is implemented in a standard CMOS $0.35{\mu}m$ processing parameter with a supply voltage of 2.5V. The HSPICE results show that the filter has 200KHz and 5MHz cutoff frequency, and each 3.4us and 85.44us gm value.
