Abstract: A method for signal strength detection begins by comparing a signal strength representation of a signal with a signal strength representation of a reference signal. The method continues by adjusting, when the signal strength representation of the signal compares unfavorably with the signal strength representation of the reference signal, at least one of the signal strength representation of the signal and the signal strength representation of the reference signal until the signal strength representation of the signal compares favorably with the signal strength representation of the reference signal. The method continues by determining signal strength of the signal based on the adjusting of the signal strength representation of the signal and signal strength of the reference signal.

Abstract: A voltage domain crossing circuit and method are disclosed. In one embodiment, the voltage domain crossing circuit comprises an AC coupling component, a DC biasing component and a high voltage output amplifier. The AC coupling component receives an input low voltage signal and AC couples and splits the signal into two voltages. The two voltages are then DC biased to a predetermined bias voltage using the DC biasing component. The high voltage output amplifier then amplifies the biased voltages in the high voltage domain yielding a signal in the high voltage domain. Other embodiments of the voltage domain crossing circuit and method are also disclosed.

Abstract: A small signal amplifier with a large signal output boost stage are connected between first and second supply rails. The small signal amplifier receives first and second input signals and provides an output signal at an output node which drives a load. Under small signal conditions, the output signal varies approximately linearly with the difference voltage. However, under large signal conditions, a rail-to-rail large signal output boost stage connected to the output node is arranged to drive the output node close to the first or second supply rail as needed to provide the current demanded by the load. The large signal output boost stage is off in small signal conditions, but comes on rapidly and transfers maximum charge to the load under large signal conditions.
