Title: Semiconductor integrated circuit device
Inventor: SAKAMOTO MASARU
IPC: H03K19/08
Filed: 1991-11-29
Abstract: PURPOSE:To reduce power supply and to attain high speed processing by forming a current corresponding to an absolute output signal level with respect to a reference potential and feeding back it to form a variable current source thereby operating a wired OR circuit. CONSTITUTION:A drain current 11 flowing corresponding to an output signal X is fed to NMOSFETs Q2, Q3 of a current mirror form and converted into an absorbing current I2. The current I2 is fed back as an operating current of the wired OR circuit. When the output signal X is going to change to an L level in response to both input signals A, B reaching an L level, a drain current of a PMOSFETQ1 increases accordingly. Then a variable current I2 is increased via a current mirror circuit. As the output signal X changes to an L level through the positive feedback loop as above, the current I2 increases and the output signal X changes quickly from an H level to an L level. Through the operation as above, low power consumption and high speed operation are attained.
