High Speed Power Efficient CGIC Digital Filters For VLSI Applications
Digital filter structures based on current-conversion generalized immittance converter (CGIC) proposed by Antoniou and Rezk possess excellent sensitivity and stability characteristics. In this paper, the CGIC structures of low pass and high pass are analyzed to determine the clock period to be used with these structures for VLSI applications and are modified to reduce the clock period further to increase the speed keeping the sensitivity and stability of these structures are exactly the same as those of the original structures. The modified filters are also power efficient while maintaining the original speed but increase the latency to some extent. With a supply voltage of 5 volts the modified filters show 33% increase in speed and 68% reduction in dynamic power consumption if supply voltage is scaled down without increasing the original speed
