  • Semiconductor device for digitizing an electric analog signal
    Patent number: 4333022
    Abstract: An analog/digital converter implemented on an MIS structure having a gate electrode in the form of a resistance layer across which the potential gradient is applied. The analog signal supplied to the gate electrode and is converted into a shift of an inversion layer below the gate electrode. The digital signal is obtained by means of determining the number of surface regions which are present below the gate electrode and which can be electrically connected to the inversion layer.

  • Threshold circuit using complementary field effect transistors
    Patent number: 4326136
    Abstract: A threshold arrangement includes two complementary transistors whose channels are situated in series between two supply terminals. In order to obtain a substantially square-wave relationship between the output voltage on the common drain electrodes and the input voltage on the interconnected gate electrodes, a direct voltage source is included between the two gate electrodes, which source has a voltage which is preferable substantially equal to the supply voltage minus the sum of the threshold voltages of the two complementary transistors.
