Abstract: A storage capacitance across which a ramp function signal is to be generated is serially related through a fixed resistor, electric signal variable-voltage solid-state device to a source of charging current. The potential developed across the capacitance is one input to a differential amplifier. Selectively variable potentiometers relate the differential amplifier output to the variable-voltage device correspondingly controlling the capacitance charging current. A further aspect is the use of back-to-back diodes for appropriate poling of the signal from the potentiometers to the solid-state device.
