Abstract
We present a new architecture for wireless power and
data telemetry that recovers power and a system clock from a weak
incident RF signal. A high-efficiency RF–DC converter generates
a 3-V
/68/67supply for the system from a
12.3-dBm incident RF
signal, gathered by a commercial 50- /10antenna. A system clock
is extracted from the same incident signal, by an injection-locked
LC oscillator. Sub-harmonic injection-locking facilitates the sepa-
ration of the incident and the transmit signal frequenci
