Abstract: A system on a package (SOP) can include a galvanic isolator. The galvanic isolator can include an input stage configured to transmit an input RF signal in response to receiving an input modulated signal. The galvanic isolator can also include a resonant coupler electrically isolated from the input stage by a dielectric. The resonant coupler can be configured to filter the input RF signal and transmit an output RF signal in response to the input RF signal. The galvanic isolator can further include an output stage electrically isolated from the resonant coupler by the dielectric. The output stage can be configured to provide an output modulated signal in response to receiving the output RF signal.

Abstract: A method is provided. An initial bit sequence is received by a receiver. A local oscillator is locked initially to a local reference and subsequently to the received signal using the initial bit sequence, and automatic gain control (AGC) is performed once the local oscillator is locked to the local reference. A Costas loop is then activated so as to achieve carrier frequency offset (CFO) lock, and sign inversion is detected. The receiver then synchronized with an end-of-training pattern.
