Abstract
A current ramp generator is provided for controlling the fall time of a bubble generate waveform of a bubble memory system. Gate circuitry is responsive to a digital input signal and provides an initializing signal to a current source. The current source charges a capacitor and thereby provides an increasing signal to a current mirror whose output sinks current from a control amplifier of the bubble memory system.
