ABSTRACT:
A programmable, low-current voltage source for small-signal electronic equipment, such as portable cellular telephones, is achievable by generating and applying a bias voltage and a reference voltage across a voltage divider circuit. Consequently, a low-current output voltage is generated at the center junction of the voltage divider circuit. Adjustment of the low-current output voltage level is accomplished by adjusting either the bias voltage level and/or the reference voltage level. The adjustment of the bias voltage level and/or the reference voltage level, in turn, is controlled by a programmable, microprocessor-based waveform generator.
