ABSTRACT:
A programmable sweep generator for generating a linear ramp signal of different slopes in a predetermined step sequence is disclosed. The programmable sweep generator comprises a controllable voltage generator, a voltage-to-current converter, and integrator sections. The slopes of the ramp signal may be electronically controlled by switching the controllable voltage generator, voltage-to-current converter and timing capacitors in the integrator section. The use of independent buffer amplifiers, independent control circuits, and current steering devices for each timing capacitor eliminates the need to connect a switching element in series with each timing capacitor, thereby eliminating any error or non-linearity.
