This circuit operates at a voltage of 1.3 V from a single mercury cell. We found in an old documentation and for the components used the frequency is 500 kHz.
This circuit has its gain controlled by voltage. The circuit, which uses discrete components, was...
In the figure we have an interesting possibility that consists of the activation of a heating...
This circuit was found in the 1974 Ferranti transistors manual. The circuit has low input...
