This linear oscillator was found in a 1968 publication. The operational amplifier is from that time. Both the FET and the integrated support current equivalents.
The circuit in the figure uses the four current amplifiers of the LM3900 to generate a sawtooth signal...
The presented circuit was suggested by the 1994 Linear Applications Handbook from National...
This circuit was found in a Motorola documentation from 1968. The load current is 10 A. The...
