This thesis presents the design and implements an adjustable complex bandpass filter with its automatic tuning loop circuit for GSM, IEEE 802.15, W-CDMA, IEEE802.11a/b/g and IEEE802.16a wireless communication standards ,and an anti-aliasing filter for GSM, W-CDMA wireless communication standards in UMC90nm 9-metal-single-poly CMOS process. The complex bandpass filter and the anti-aliasing filter are used in the Low-IF receiver architecture and the direct-conversion receiver architecture, respectively. Both filters can be used in Software Defined Radio (SDR) receivers, and operate in variety of wireless communication standards.
The complex bandpass filter is based on transconductor-C integrators, and changing bandwidth by different cap array values of filter to operate in various wireless communication systems. There are two operating modes in the complex bandpass filter where the -3dB bandwidths range from 153.1 KHz to 1.53 MHz (low frequency mode) and from 4.28 MHz to 70.9 MHz (high frequency mode). The power consumption of low frequency mode and high frequency mode are 2.61mW and 10.17mW, respectively, and the chip area is 1.99mm2(1.53mm×1.3mm). Automatic tuning loop is used for decrease the inaccuracy of the active filter bandwidth due to process variation. Tuning method is implemented in the master-slave architecture, and the cap array values of filter are determined by Successive Approximations method to self-calibrate the bandwidth of complex band filter. The power consumption of automatic tuning loop circuit is 2.45mW, and the chip area is 0.8mm2 (0.615mm×1.3mm).The anti-aliasing filter consists a transconductor-C filter and a decimation filter. It can suppress interference from adjacent channel and remote channel. The power consumption of anti-aliasing filter is 2.74mW, and the chip area is 1.12mm2 ( 1.02mm×1.17mm ).
