A–102-dBm Sensitivity Multichannel Heterodyne Wake-Up Receiver With Integrated ADPLL

open access: yesIEEE Open Journal of the Solid-State Circuits Society
This article presents a binary frequency-shift keying (BFSK) heterodyne wake-up receiver (WuRx) with -102-dBm sensitivity at 2.4 GHz. An integrated low-power all-digital phase-locked loop (ADPLL) allows sharp filtering at the intermediate frequency (IF ...

Digital phase-lock loop having an estimator and predictor of error [PDF]

open access: yes, 1988
A digital phase-lock loop (DPLL) which generates a signal with a phase that approximates the phase of a received signal with a linear estimator. The effect of a complication associated with non-zero transport delays related to DPLL mechanization is then ...
