Abstract: A dynamic logic gate has a device for charging a dynamic node during a pre-charge phase of a clock. A logic tree evaluates the dynamic node with a device during an evaluate phase of the clock. The dynamic node has a keeper circuit comprising an inverter with its input coupled to the dynamic node and its output coupled to the back gate of a dual gate PFET device. The source of the dual gate PFET is coupled to the power supply and its drain is coupled to the dynamic node forming a half latch. The front gate of the dual gate PFET is coupled to a logic circuit with a mode input and a logic input coupled back to a node sensing the state of the dynamic node. The mode input may be a slow mode to preserve dynamic node state or the clock delayed that turns ON the strong keeper after evaluation.

Abstract: A threshold voltage measurement device is disclosed. The device is coupled to a 6T SRAM. The SRAM comprises two inverters each coupled to a FET. Power terminals of one inverter are in a floating state; the drain and source of the FET coupled to the inverter are short-circuited. Two voltage selectors, a resistor, an amplifier and the SRAM are connected in a negative feedback way. Different bias voltages are applied to the SRAM for measuring threshold voltages of two FETs of the other inverter and the FET coupled to the other inverter. The present invention uses a single circuit to measure the threshold voltages of the three FETs without changing the physical structure of the SRAM. Thereby is accelerated the measurement and decreased the cost of the fabrication process and measurement instruments.
