This work presents a fully-integrated double-quadrature Weaver receiver for monitoring the NIST time and frequency reference radio station WWV across multiple channels in the 2.5-20 MHz range. The design takes advantage of the Weaver architecture's elimination of image rejection filters. The receiver uses a broadband low-noise amplifier (LNA) with an input-referred noise power spectral density (PSD) of <2.25nv/Hz^1/2 for high sensitivity. Instead of large filters, a double-quadrature down-conversion process is used to remove the image signal. Both local oscillators (LOs) are frequency- and phase-locked to each other via an on-chip frequency divider, and their I and Q components are generated by highly-precise digital phase splitters. The receiver was fabricated in the TSMC 180nm CMOS process and consumes 24.9 mW. Measurements show in-band gain >40 dB, noise figure (NF) <2.9 dB, and maximum image rejection ratio (IRR) of 29 dB without calibration.
