An enhanced glitch eater circuit for eliminating glitch signals occurring within a predetermined period from a raising edge or a falling edge of a signal pulse is comprised of an inverter connected to a transmission gate which is controlled by a two-input XNOR (exclusive-NOR) gate receiving a latched signal at one input and a delay latched signal at the other input, the latched signal being from the output of the transmission gate. The latched signal may be reset by a transistor.

Enhanced glitch removal circuit

A flip-flop for storing a bit of digital information generally used in register architectures is comprised of a two-input NAND gate and a D-type flip-flop. The output of the NAND gate is connected to the clock terminal of the flip-flop and the data signal is directed to the data terminal of the flip-flop. A new clock scheme is provided with for this circuit configuration in order to properly store the data signal.
