Title: Bias voltage generating circuit and semiconductor integrated circuit device
Inventor: KATSUHISA TAKUJI
IPC: H01L21/822
Filed: 2002-04-24
Abstract: <P>PROBLEM TO BE SOLVED: To improve a bias voltage output by reducing the decrease of a bias voltage output due to the threshold voltage of an MOS transistor.  <P>SOLUTION: When a CLK is changed to a high level, a CKA is increased to a VCC potential, and a CKB is decreased to a GND potential. Thus, the potential of wiring 12 is decreased from a 2VCC potential to the VCC potential, and an NT4 is turned off. When a CKC is increased to the VCC potential later, the potential of wiring 13 is increased only by the VCC to the 2VCC potential. Then, when a clock signal CKD is increased to the VCC potential, the potential of wiring 14 is increased from the VCC potential to the 2VCC potential, and an NT5 is turned on so that the potential of a bias voltage output terminal VOUT can be increased to 2VCC-(Vt+ΔV).  <P>COPYRIGHT: (C)2004,JPO
