1. signal generator
electronic devices that
generate repeating or
non-repeating
electronic signals

2. ICL8038

3. Working of ICL8038
•Capacitor C
•Current source #1
•Current source #2 (OFF)
•Capacitor charges with current I
•Comparator 1 = 2/3 of input voltage
•Flip flop is triggered
•Current source #2 (ON) current 2I
•Capacitor discharges with current I
•Comparator 2= 1/3 of input voltage
•Flip flop is resetted
•Cycle gets repeated

• Frequency range C1 value
1Hz – 100Hz=1uF
100Hz-1KHz=0.1uF
1KHz-10KHz=0.01uF
10KHz-100KHz=0.001uF
• The components list
Resistors size 1/4W 5%
R1=2.2K
R2=10K
VR1=10K Single potentiometer
Capacitors

Oscillator

9. Applications
• The waveforms can be injected into a device under
test and analyzed as they progress through
it, confirming the proper operation of the device or
pinpointing a fault in it.
• Like Using it to test any measurement
equipment, apply signals as input to electronic
circuits.
• to calibrate a microphone setup.
