This paper presents the design of a variable gain amplifier (VGA) to be used in a reconfigurable receiver for wireless applications. The gain of the block can be digitally programmed between 0 and 35 dB, with a uniform step of 2.5 dB, while satisfying the noise and linearity requirements of WLAN, UMTS and GSM standards. The cutoff frequency of the system can be selected according to the processed standard (15 MHz for WLAN and UMTS, 5 MHz for GSM). Special care is taken in reducing the current… CONTINUE READING
