Abstract :
A low-power tunable LC bandpass filter is introduced for radio-frequencies applications. Center frequency of the filter can be tuned over a range of 144 MHz around 2 GHz at high quality factor (Q). Input signal is given to the LC resonator by an on-chip transformer, which reduces the power-consumption to 1 mW at a Q of 81. The Q-factor can also be tuned up to 150 when the center frequency remains at 2 GHz. Dynamic range of the filter is more than 50 dB with 1.2 V supply voltage. Modeling of the proposed filter and simulation results produced using IBM CMOS8RF 0.13 mum technology are presented
