Patent ID: 8306178

Claim:
A vMOS based multi-value counter unit, comprising: a vMOS source follower, comprising, a first control gate; a second control gate; and a third control gate; and a trigger circuit, comprising, a first dual-value D flip-flop with a first flip-flop input terminal, a second flip-flop input terminal, a first flip-flop output terminal, and a second flip-flop output terminal; a second dual-value D flip-flop with a third flip-flop input terminal, a fourth flip-flop input terminal, a third flip-flop output terminal, and fourth flip-flop output terminal; an AND gate with a first AND gate input terminal, a second AND gate input terminal, and an AND gate output terminal; and an OR gate with a first OR gate input terminal, a second OR gate input terminal, and an OR gate output terminal; wherein said second flip-flop input terminal receives a clock signal, said fourth flip-flop input terminal receives said clock signal, said fourth flip-flop output terminal outputs to said first flip-flop input terminal, said first flip-flop output terminal outputs to said third flip-flop input terminal and said first OR gate input terminal, said second flip-flop output terminal outputs to said second AND gate input terminal, said third flip-flop output terminal outputs to said first AND gate input terminal and said second OR gate input terminal, said third flip-flop output terminal further outputs to said second control gate, said AND gate output terminal outputs to said third control gate, and said OR gate output outputs to said first control gate.
