This paper presents an improved high-gain amplifier circuit with low-frequency servo loop to remove DC offset and 1/f noise in UHF RFID receiver. Compared to AC coupling amplifier, the circuits can overcome DC saturation and reduce the distortion of the baseband signal in various data rate. Based on the UHF RFID data rate as example, the paper gives the circuit design model and detailed parameters, and the simulation and practical experiments are carried out to validate the circuit model.
