Title: Semiconductor device
Inventor: MIYASHITA TAKUMI
IPC: H01L27/092
Filed: 1989-05-26
Abstract: PURPOSE:To protect the transistor gate of a protective circuit against dielectric breakdown and to prevent a leak to a substrate/wafer even if a high voltage is applied to a pad by a method wherein the gate of the MOS transistor of an electrostatic protection circuit is connected to a well, not to a power source. CONSTITUTION:A semiconductor substrate is of P-type, and a P channel transistor Q1 is formed on an N well. In this case, an N channel transistor Q2 can be directly formed on the substrate, but in an IC of twin tab type, a P well slightly higher than a board in concentration is formed, and the N channel transistor Q2 is formed on the P well. The gates of the P and the N channel transistor, Q1 and Q2, are connected to an N well and a P well respectively instead of a high potential power source Vcc and a low potential power source Vss. By this setup, even if a voltage is applied to a pad, the transistor gate of a protective circuit is protected against dielectric breakdown and a leak to a board/wafer can be prevented.

IPC: H04N5/93
Filed: 1987-05-29
Abstract: PURPOSE:To always ensure the optimum noise canceling value by using a noise level detecting circuit and a limit changing means and controlling the limit so as to obtain the minimum necessary offset value. CONSTITUTION:A limit circuit 14a contains a noise cancel control circuit 25 which detects a noise level from the mean amplitude of the noise component to cancel the noise deep after increasing the amplitude of the noise component offset by a subtractor 16 or the limit of the frequency band width in case the noise level is high and then to reduce said limit to cancel the noise shallowly with a low noise level respectively. Then the minimum necessary noise cancel value is secured by the circuit 14a. Thus the input of the valid component is reduced to the subtractor 16 and therefore this valid component is never offset. Then the proper noise canceling value is always secured.
