Abstract :
A constant slope integrator for single integration linear delta modulation (LDM) will be described. The circuit essentially is a bootstrapped sweep generator, capable of generating positive and negative sweep voltages. It uses one transistor, four diodes, and two Zener diodes. The step size can be easily changed by changing the base resistance or charging capacitance. The circuit is versatile and may be used effectively in other waveform generators. The circuit is integrable.
