Title:
SEMICONDUCTOR CIRCUIT
Document Type and Number:
Japanese Patent JP2005198240
Kind Code:
A
Abstract:
To provide a semiconductor circuit, capable of effectively applying a filter function to both the "L-level" noise superimposed during originally "H" signal periods and "H-level" noise superimposed during originally "L" signal periods.
An input signal IN branches off into two signals, and one of them is inputted via a signal inversion means 4 to a first delay circuit 1 including a first capacitor 14. The other signal is inputted to a second delay circuit 2 including a second capacitor 18. An output signal from the first delay circuit 1 and an output signal from the second delay circuit 2 are inputted to separate input terminals of a flip-flop 3.
