Abstract
A method of enhancing the performance of an inductive boost amplifier includes the steps of detecting the specific load impedance being drive by the amplifier, and adjusting the operation of the amplifier to accommodate the detected load impedance. Various load impedances may be connected to the improved amplifier while accommodating the impedance of different amplifier loads subject to change under various conditions such as temperature, voltage, frequency, etc. Thus, in addition to compensation of static load impedance variances, the present invention is quite effective in compensating for dynamic variances as well. Although the description focuses on variable load impedance compensation, it is anticipated that simpler implementations of the technique may be used to selectively switch output filter components into operation in response to specific load impedance ranges, yielding a similar, albeit coarser, net result. The invention may be used as well to regulate other amplifier functions, such as back-EMF shunt timing, and other circuits.
