Abstract
a first flip flop (24) which has falling edge signal as the input; a second flip flop (21) which has falling edge signal as the input; a third flip flop (22) which inputs the positive output (Q) of the second flip flop (21); a first NAND gate (31) which supplies the NAND result of positive output (Q) of the second flip flop (21) and the negative output (Q bar) of the third flip flop (22) to CLK of the first flip flop (24) as trigger pulse; a forth flip flop (23) which inputs the output of the NAND gate (31) and delays it; a voltage comparator (25); an inverter (26) which receives FFo; a first AND gate (27) which receives the output of the voltage comparator and the inverter; a second NAND gate (30) which receives the output of the first AND gate and the forth flip flop; an OR gate (29) which receives the output of the second NAND gate and the positive output (Q) of the opposite first flip flop (24); a second AND gate (28) which receives the output of the OR gate (29) and the output voltage (Vcc).
