A Switched-Capacitor Filter with A Slew Rate Enhancement Technique

In this paper, a switched-capacitor filter with a slew rate enhancement circuit for wireless communication applications is designed. The type of the filter is chosen the 5 th -order Elliptic lowpass filter to implement over 43dB of stopband attenuation at the 1.4 times frequency of passband. For direct conversion transceiver applications, the DC offset canceling circuit and programmable gain amplifier are included. The filter is fabricated in a 0.35-μm CMOS 2P4M technology. The power dissipation is 14.7mW for a single supply voltage of 3 V.
