University of California, San Diego, CA 1 Accurate and stable frequency-management modules (FMMs) are a critical component in wired/wireless communication systems since they determine key metrics such as data rate and bit-error rate. Conventional FMMs utilize a crystal reference to stabilize a frequency synthesizer with configurable output frequencies, as shown in Fig. 4.2.1 (top). However, using a bulky off-chip crystal can, in some cases, add too much cost and/or size for small IoT applications. Replacing the crystal with other off-chip references based on MEMS/BAW/SAW-type structures [1] doesn’t quite solve this problem; the best solution would be full on-chip integration. However, on-chip frequency references, commonly
