PROBLEM TO BE SOLVED: To solve a reset pattern noise problem with a simple circuit and solitary control signal. SOLUTION: A complementary metal oxide semiconductor (CMOS) imager flush reset circuit 400 is provided. The flush reset circuit 400 has an interface to receive first (e.g., VDD) and second (e.g., ground) reference voltages. The flush reset circuit 400 has a solitary (flush) signal interface. There is also an interface connected to a transistor set power interface to receive a flush1 signal, and in response to receiving the flush signal, the interface supplies Vflush1 signal at least one threshold voltage different from the second reference voltage. The flush signal is used to create a CMOS imager hard reset prior to a soft reset. COPYRIGHT: (C)2009,JPO&INPIT
