Abstract：
A novel digital programmable gain amplifier (PGA) is proposed in this paper. The proposed design avoids the gain accuracy affected by on-resistance of control switches, leading to much more accurate gain. The cor-responding algorithm is shown in this paper. The circuits are implemented in CSMC 0.35 μm Technology. When the gain is from 0dB to 20dB, step is 2dB; from 0dB to -20dB, step is 20dB. It is concluded that the difference of the gain between simulation result and theoretical value is within ±0.05 dB. © 2014 IEEE.
