Abstract
A logic circuit of a ratioless structure, wherein a load MOS FET, a drive MOS FET and a pre-discharge MOS FET are connected in series in the described order, a first clock is applied to the pre-discharge MOS FET, a second clock is applied to the load MOS FET, and an input signal is applied to the drive MOS FET while an output signal is derived from the junction between the drive MOS FET and pre-discharge MOS FET.
Claims3
A logic circuit of a ratioless structure comprising:
- an input terminal;
- a drive MOS FET having its gate connected to said input terminal;
- a pre-discharge MOS FET having its drain connected to the source of said drive MOS FET and its gate arranged for reception of a first clock pulse signal which causes a pre-discharge of charges accumulated at the drain of said pre-discharge MOS FET;
- a load MOS FET having its source connected to the drain of said drive MOS FET and its gate arranged for reception of a second clock pulse signal;
- and
- an output terminal connected to the junction between the source of said drive MOS FET and the drain of said pre-discharge MOS FET.
