A low-power and low-voltage super-regenerative receiver operating at 1 GHz and implemented in a 0.35-μm CMOS process is described. The receiver includes an low-noise amplifier, a super-regenerative oscillator, an envelope detector, an AGC circuitry with sample/hold function, and a baseband amplifier. The die surface is equal to 0.25 mm2. The power consumption is less than 1.2 mW at VDD = 1.5 V. A 100-KHz saw tooth quench signal is used to achieve a rejection of -36 dB at 500 KHz from the central frequency.
