Claim 8:
9. The multi-branch AC-mode bridge of claim 1, wherein:
the K branches are one of M sets of K branches, each set of K branches to couple with a respective one of M channel sets, each channel set being a disjoint set of K touch sense channels of the touch panel array, M being an integer greater than one;
the error amplifier is one of M error amplifiers, each to generate a respective one of M error signals responsive to the sinusoidal driver signal and the channel feedback signal; and
the K adjustable current sources are one of M sets of K adjustable current sources, each of the M sets of K adjustable current sources to output a respective set of K sinusoidal input currents to a respective one of the M sets of K branches based on a respective one of the M error signals.
