This 80's circuit uses an audio amplifier to obtain a symmetrical source from a single source. The maximum current is on the order of 1.3 A and the input voltage must not exceed 20 V.
This circuit provides a linear attenuation of a signal up to 100 dB. The circuit operates with...
This high impedance circuit for low voltage sensors was found in a 1980s documentation. The JFETs...
We found this circuit in a 1989 publication. Its purpose is to produce noise in the VHF or UHF...
