title = "A Novel Wideband Programmable-Gain Amplifier based on Active-Feedback Technology",
abstract = "A new type of approach for programmable-gain amplifier (PGA) design with wideband and accurate dB-linear characteristic is presented. This circuit is based on the active-feedback bandwidth extension circuit structure, and the variation of voltage gain of this circuit can approach the pseudo-exponential function by using a binary-weighted switching technique without additional exponential generator. Therefore, compared with the traditional circuits, the proposed circuit can achieve wider-3dB bandwidth while obtaining wide digital dB-linear gain control, smaller gain error, smaller chip area and lower power consumption. The proposed PGA is simulated in a standard 0.18\mu\mathrm{m} CMOS technology. The gain ranges from-3.87 dB to 3.57 dB with a gain error less than ±0.017 dB. The frequency is almost flat up to 1GHz. The NF is around 12 dB and it consumes about 6.5 mW under a 1.8 V power supply.",
