A tunable, high-Q RF filter suitable for wireless transmitters has been implemented in a standard digital 0.18-mum CMOS technology. Active circuits are used to enhance the Q of two independent LC resonators, which are cascaded to form a wide bandwidth filter that can be tuned in both center frequency and bandwidth. A 5.145-GHz stagger-tuned filter with a 200-MHz bandwidth and 0.8 dB of ripple is demonstrated in an 802.11a sliding-IF transmitter. The transmitter provides spectral mask and EVM… CONTINUE READING
