Title: VOTING CIRCUIT AND SELF-CORRECTING LATCHES
Abstract:
The disclosed voting circuit includes a pull-up circuit (110) connected to an output node (126) and to a positive supply voltage (122). A pull-down circuit (112) is connected to the output node (126) and to ground (124), and the output node (126) is coupled to receive true output of a first bi-stable circuit (104). The pull-up circuit (1 10) pulls the output node (126) to the positive supply voltage in response to complementary output signals from second (106) and third (108) bistable circuits being in a first state, and the pull-down circuit (1 12) pulls the output node (126) to ground (124) in response to complementary output signals from second (106) and third (108) bi-stable circuits being in a second state that is opposite the first state.
