1. A driver circuit capable of receiving an input signal having an x-component, a y-component, and a z-component, comprising:
a first circuit portion comprising:
a first sub-circuit configured to receive the input signal and compute:
a first angle based on the y-component and the x-component;
a second angle based on the z-component and the x-component; and
a third angle based on the y-component and the z-component;
a second sub-circuit connected to the first circuit and configured to:
assign, from a plurality of zones, a first zone to the first angle, a second zone to the second angle, and a third zone to the third angle; and
a third sub-circuit connected to the second sub-circuit and configured to produce an output gain according to the first, second, and third zones; and
a second circuit portion connected to the first circuit portion and configured to apply the output gain to the input signal.
