Abstract
A method of adaptively operating a transmit detection circuit is presented. The method includes powering the transmit detection circuit with a capacitor charged by an LDO; receiving a digital ping signal from a transmitter; receiving a clock signal from a local oscillator; updating a register to accommodate timing of the digital ping signal; and generating a signal indicating whether the transmitter is present.
