Abstract

This work presents an improved design of the current amplifier based optimal complex filter providing fully electronically programmable characteristics. It extends the tuning features to include the pole frequency and the gain in addition to the center frequency. The new solution avoids the employment of capacitor and/or resistor banks leading to a more compact design solution while maintaining comparable power consumption. Simulation results obtained from a 0.18μm standard CMOS process show that the proposed design can be used to accommodate several short range communication applications such as Bluetooth and ZigBee, as well as several mobile TV standards such as Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) and Terrestrial Digital Multimedia Broadcasting (T-DMB). Performance characteristics of proposed design in terms of dynamic range and image rejection ratios are also provided.
