A CMOS RF RMS detector is introduced. It generates a DC proportional to the RMS voltage amplitude of an RF signal. Its high input impedance and small silicon area make it suitable for the built-in testing (BIT) of critical RF blocks of a transceiver such as a Low Noise Amplifier (LNA) and Power Amplifier (PA) without affecting their performance and with(More)
This project involves the design of a CMOS RF RMS Detector that converts the RMS voltage amplitude of an RF signal to a DC voltage. Its high input impedance and small area make it suitable for the built-in-testing of critical RF blocks of a transceiver such as a Low Noise Amplifier (LNA) and Power amplifier (PA) without affecting their performance and with(More)
Multi-frequency signal recursion allows for efficient reuse of transconductance in a radio receiver, which helps to reduce power dissipation. An I-Q receiver based on the recursive principle is demonstrated here. The design employs a self-biased load, with chopping at baseband in order to minimize low-frequency in-band flicker noise. The bias setting of the(More)
A low-power Weaver image-reject receiver based on 3rd-order signal recursion is demonstrated. The design employs two downconverters and seeks to enhance the dynamic range and gain-bandwidth product per unit power dissipation metric by adopting recursive gain reuse at multiple frequencies. Utilizing an LO at frequency f<sub>LO</sub>, the downconverter(More)
