Title: Semiconductor device
Inventor: TERADA YASUSHI
IPC: H03K19/017
Filed: 1983-05-18
Abstract: PURPOSE:To hold a high voltage developed at an output terminal constant without any drop with time by providing the 1st and the 2nd transistor (TR) and a capacitor which is connected to the node at one electrode and to a control signal line for the 2nd control signal at the other electrode. CONSTITUTION:The capacitor 14 is connected to the node 11 at one electrode and to the control signal line 15 for the control signal phi2 at the other electrode. When a charge pump current is supplied as a signal 13 firstly, a control signal phi1 is held at a level ''H'' (e.g. source voltage Vcc) to turn on a transistor (TR)9. When the control signal phi2 falls to a level ''L'', the node 11 is at a potential Vcc-Vth, where Vth is the threshold value of the TR. Then, when the control signal phi2 goes up to ''H'' again, the potential at the node 11 rises to 2Vcc-Vth. Thus, the control signal phi2 varies between the levels ''H'' and ''L'' repeatedly to hold the signal line 13 at the high voltage for a long time even if a leak occurs to the signal line 13.
