ABSTRACT:
A sense circuit has input and output terminals coupled through resistances to two fixed potentials. The input potential is amplified and inverted to control the gate of a field-effect transistor coupled between the input and output terminals. Alternatively, a sense circuit has first and second input terminals, and first and second output terminals. The first input terminal is connected to the gate of a depletion-mode field-effect transistor coupled between the second input and output terminals. The second input terminal is connected to the gate of a depletion-mode field-effect transistor coupled between the first input and output terminals. The depletion-mode field-effect transistors may be replaced by negative-resistance circuits. These sense circuits can obtain large voltage outputs from small current inputs.
