Soft-error rate improvement in a latch using low-pass filtering |
摘要 |
In a preferred embodiment, the invention provides a circuit and method for reducing soft error events in latches. A low-pass filter is placed between the output of a forward inverter and the inputs of a feedback keeper. The first and second outputs of the low-pass filter are connected to first and second inputs respectively of the feedback keeper. The only type of diffusion connected to the first output of the low-pass filter is a P-type diffusion. The only type of diffusion connected to the second output of the low-pass filter is an N-type diffusion. The feedback keeper is connected to an input of the forward inverter.
