Abstract
In this thesis, a tunable inductorless CMOS narrow-band bandpass filter at UHF (ultra-high-frequency, 300MHz-3GHz) band is presented. Issues related to active-inductor design and filter design procedure is discussed in detail. The filter is fabricated in 0.18μm CMOS process, measured an insertion loss of 0.1dB, a return loss of 18dB and a 0.51dB in-band ripple with a 436MHz center frequency and 24MHz bandwidth. The filter occupies a chip size of 333 x 653 μm2, with a -27.1dBm input 1dB compression point , a 17.6dB noise figure and a 62.5 mW power consumption.
