This paper reports a current-reused pseudo-differential (CRPD) programmable gain amplifier (PGA) that demonstrates small size, low power, wide band, low noise, and high linearity operation with 4 control bits. Implemented in 0.18um CMOS technology, the PGA shows the gain range from -9.9 to 8.3 dB with gain error of less than +/- 0.38 dB. The IIP3, P1dB, and smallest 3-dB bandwidth are 10.5 to 27 dBm, -9 to 9.5 dBm, and 250 MHz, respectively. The PGA occupies the chip area of 0.04 mm(2) and consumes only 460 mu A from a 1.2V supply.
