Abstract :
This paper presents a 6th-order switched capacitor lowpass filter implemented in 0.35 μm CMOS for baseband channel selection in direct conversion Universal Mobile Telecommunications System (UMTS) receiver. The filter selects a 2 MHz channel and attenuates by at least 51 dB from 2.9 MHz to 10 MHz. It presents a passband ripple less than 0.35 dB
