Abstract
A RF receiver with extremely low standby power consumption. To minimize power consumption during standby, the analog input from the antenna circuit (including tank resonator) is connected directly to the inputs of a comparator. Preferably two comparators are used, each connected to a separate antenna. Thus, a signal loss due to antenna nulls will be minimized. Preferably a following stage decodes a pulse-width-modulated (or burst-length-modulated) signal. If the length of pulses substantially exceeds the expected maximum, the following stage provides a control signal to reduce the gain of the input comparators.
