Voltage Ramp Generator. The output will slew to within the diode forward voltage divided by the gain of u2 that is 1 r3 r4. Being that this waveform repeats over and over again this generator can be seen as an oscillator.
555 ramp generator chapter 6 analog integrated circuits pdf version. Be sure you connect this capacitor in the circuit properly. The ramp is generated by a constant charging current into capacitor c ramp which is connected between ground and the noninverting input of op amp ic1 configured as a voltage follower.
The ramp is generated by a constant charging current into capacitor c ramp which is connected between ground and the noninverting input of op amp ic1 configured as a voltage follower.
This waveform increases steadly as the capacitor is being charged until it hits its peak and then decreases even more dramatically as the capacitor is discharged. Be sure you connect this capacitor in the circuit properly. If the input voltage v 1 is constant and rc 1 s then the output voltage v o after a time t is given by v o v i t. A ramp generator is a signal generator which generates a ramp waveform.
