This paper mainly studies a signal processing methodology of communication systems realized circuits of Adaptive Delta Modulation (ADM) using Operational Transconductance Amplifiers (OTAs). Methodology: This work suggests a design for adopting the quantization step size using feedback output quantize through adoptive delta modulation scheme using loss operation with Transconductance amplifier as loss OTAs integrator. Quantization step size is realized using integrators, rectifiers and amplifiers. The step over load is controlled by variable voltage gain (Av) of the Trans conductance. Result: was compared with conventional ADM using Op-Amp. According to the quantized output, the slope overload noise and granular noise are changed by controlling the variable voltage gain (Av) of OTAs. Conclusion: The paper suggests a design using feedback output quantize through ADM scheme by loss operation with Trans-conductance amplifier as loss OTAs integrator, the control is achieved by increasing or decreasing the step size from δmin to δmax in order to determine the quantization noise. Simulation power results improve the signal-to-noise ratio (SNR) and modulation quality at fs = 64 kHz. Moreover, the dynamic range of the modulator is also improved.
