A signal generating circuit including a constant current source comprising cascoded field effect transistors. The first transistor is biased into saturation and the second transistor is biased in the linear resistive region of operation. Degenerative feedback is provided between the output of the first transistor and the control electrode of the second transistor. When an energy storage device and a switch are added, the circuit provides a constant amplitude ramp waveform.
