A Simulation of A Complex Microelectronic Module Containing Analogue and Digital Elements,

Abstract

The report describes an attempt to simulate the complex functions present in a Delta Sigma Speech Coder based on the G.E.C. Mk 3 coder. The simulation is flexible allowing parameters such as supply volts, temperature, clock rates, and frequency and amplitude of the analogue signal to be varied, and show the resulting effects on the final digit stream. Details are also included for circuit improvements, resulting from the simulation, to give increased dynamic range to the coding process. Comparison between the simulated parameters and those measured on a smaple coder gave a close correlation. This led to a fuller understanding of the operation of what is essentially a complex oscillating feedback circuit.
