Title: Schmitt circuit
Inventor: TAKORI MASAYUKI
IPC: H03K3/353
Filed: 1988-10-13
Abstract: PURPOSE:To stably operate a circuit to a low voltage as twice as the threashold voltage VT of a MOSFET by changing the size of a p-MOSFET and an n- MOSFET in a CMOS inversion circuit by the MOSFET being controlled by the output of a Schmitt circuit and operated as a switch. CONSTITUTION:The p-MOSFET 2 and the p-MOSFET 4, and the n-MOSFET 3 and the n-MOSFET 7 are connected in parallel, respectively by the p-MOSFET 5 and the n-MOSFET 6 controlled by the output signal of the Schmitt circuit to generate Schmitt width. In some cases, a difference is generated between a threshold voltage VTL and a threshold voltage VTU. Thereby, it is possible to operate the circuit with a source voltage up to the voltage VDD as twice the threshold voltage VT of the MOSFET since the source potential of the p-MOSFETs 2 and 4 and the n-MOSFETs 3 and 7 are directly connected to power sources VDD and VSS even when the voltage of the power source VDD is decreased.

Abstract: PROBLEM TO BE SOLVED: To easily evaluate the performance of a sonar device at a shallow sea region in a deep sea region by simulating the environment of the shallow sea region with a number of irregular reflections at the deep sea region with less irregular reflections of sound waves. SOLUTION: A control circuit 7 sets the amount of delay of delay circuits 8 and 9 and the gain of gain control circuits 10 and 11 so that a synthesis wave arrives from a known reflection position at the bottom of the sea. Also, the control circuit 7 sets the amount of delay corresponding to the amount of delay from a direct wave to the delay circuits 8 and 9 when a sound wave from the sound source arrives at the sonar device after being reflected from the bottom of the sea to be simulated.  Therefore, a sound wave radiator 3 generates a direct wave based on a signal being transmitted from a sound source signal generation circuit 1 without going through a delay circuit and at the same time the synthesis wave of the sound wave being radiated by the sound wave radiator 3 based on a signal through the delay circuit 8 and the sound wave being radiated by the sound wave radiator 14 becomes a simulated reflection wave.
