Embodiment Construction
[0017] Below with the accompanying drawings ( figure 1 ) to illustrate the present invention.
[0018] Such as figure 1 As shown, a programmable anti-interference synchronous flip-flop is characterized in that it includes a reference point detection comparator CM1 in which the positive input terminals "+" are connected to each other and the negative input terminals "-" are connected to each other, and a positive input terminal "-" is connected to each other. The hysteresis comparator CM2 and a negative hysteresis comparator CM3, the positive input terminals "+" are all connected to each other to connect the input signal Vin; the output terminals of the reference point detection comparator CM1 are respectively connected to the working power supply Vdd and The counter is interconnected with the control logic circuit; the output terminal of the positive hysteresis comparator CM2 is respectively connected to one end of the first resistor network and the control logic circuit, and...
