Impedance load driving circuit
First Claim
1. A load driving circuit for supplying a load current proportional to an input signal in order to drive an impedance load, said load driving circuit comprising:
- current detecting means for generating a load current signal representing a magnitude of a load current flowing through said impedance load;
voltage supply means for producing a voltage signal corresponding to a difference between said load current signal and said input signal, and for supplying said voltage signal to a first end of said impedance load; and
inverting voltage supply means for inverting said voltage signal, and for supplying an inverted said voltage signal to an opposite end of said impedance load.

Abstract
A load driving circuit for supplying a load current proportional to an input signal to drive an impedance load. The load driving circuit includes a current detecting circuit for generating a load current signal representing a magnitude of a load current flowing through the impedance load, a voltage supply for producing a voltage signal corresponding to a difference between the load current signal and the input signal and for supplying the voltage signal to a first end of the impedance load, and an inverting voltage supply for inverting the voltage signal and for supplying an inverted the voltage signal to an opposite end of the impedance.
