This circuit generates a sinusoidal signal with only -80 dB THD. The circuit was found in a 90's EDN. The frequency is 25 kHz and the components used are from that time.
This circuit was obtained from the Texas Instruments component datasheet which can supply currents of...
The circuit shown is a white noise generator using a zener diode as a source of noise. The...
We found this touch switch in a 1992 Electronics Handbook. The circuit can be assembled with 6 or...
