Abstract:This paper presents a VHF (30-300 MHz) RF programmable gain amplifier (PGA) with an adaptive phase correction technique. The proposed technique effectively mitigates phase errors over the VHF band, and the RFPGA as a whole satisfies all the specifications of the China mobile multimedia broadcasting VHF band applications. The RFPGA is implemented with a TSMC 0.25 m CMOS process. Measurement results reveal a gain range of around 61 dB, an IIP3 of -7 dBm at maximum gain, a power consumption of 10.2 mA at maximum … Show more
