Abstract
A method, receiver and system for isolated wireless data transfer are disclosed. The receiver includes a switching mixer connected to receive a data signal and a local oscillator signal and to output a mixed differential signal, a programmable gain amplifier using an operational transconductance amplifier (OTA) and resistive feedback, the OTA connected to receive the mixed differential signal and to provide an amplified differential signal to a polyphase filter, and an analog demodulator to demodulate the output of the polyphase filter and provide digital output.
