Abstract
This paper presents a robust super-regenerative receiver (SRR), which is insensitive to the temperature variations. A constant-alpha biasing circuit is proposed to make the start-up oscillation and start-up time of the VCO immune from temperature drifts. The prototype chip is measured in the range of -20 degrees to 90 degrees (Celsius) to verify this functionality of the constant-alpha biasing circuit. Besides, another new perspective on the detection level is proposed to derive the lowest BER. This SRR is fabricated in UMC standard 0.18μm CMOS process, and the chip area is 1.65mm × 1.45mm.
