  • Circuit to prevent pirating of an MOS circuit
    Patent number: 4583011
    Abstract: A method and circuit arrangement are disclosed for foiling an attempt to copy an MOS integrated circuit by implementing in the circuit an additional pseudo MOS device, which from its location in the circuit would appear to a would-be copier to be an enhancement-mode device. However, the pseudo-auxiliary MOS device is implemented as a depletion-mode device and is connected in the circuit so that when it is implemented by the copier as an enhancement-mode device. the overall circuit will not be functional.

  • Clock generator
    Patent number: 4547684
    Abstract: A clock generator for producing nonoverlapping clocks from an input clock includes an MOS depletion-mode device receiving the input clock at an input. The output of the depletion-mode device, which constitutes one of the clocks, is also applied to one input of a NOR gate, the other input of which is the input clock. The output of the NOR gate is the second clock.
