Abstract: This paper presents a low cost high performance of function generator and a delta modulator circuits using bidirectional tunable current technique. The tunable current technique accessed to be controlled the harmonic on output signal modulation and changing voltage across a capacitor to be linearity as ideal integrator of delta modulator model. This circuit is used to be either a square wave and triangle wave generator, it's can vary on 5 decades of frequency when it has zero input signal. Or a delta modulation when there is sinusoidal wave input signal, Moreover, This circuit consisted a few component and another achieved these objective are minimized of circuit complexity. Both analytical and experimental verifications was carried out for function generator and a delta modulator circuits using bidirectional tunable current technique.
