A1012 TRANSISTOR EPUB


According to another aspect of the present invention, in a semiconductor integrated circuit including a supply voltage a1012 transistor, a ground voltage line, a virtual ground voltage line, a logic circuit coupled to the supply voltage line and the virtual ground voltage line, a a1012 transistor for controlling current flow to the logic circuit during an active and standby mode is provided, the method comprising the steps of providing a sleep transistor coupled to the virtual ground voltage line and the ground voltage line for controlling current flow to the logic circuit; and controlling the sleep transistor over a period of time to non-abruptly set the logic circuit to the active mode.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail.

A novel turn-on mechanism, e. The turn-on mechanism according to embodiments of the present invention reduces the magnitude of voltage variation in a supply voltage VDD and ground voltage GND, as well as the time required to stabilized them. The turn-on mechanism of the present invention is implemented either by dynamically controlling the gate-to-source voltage, VGS, of a sleep a1012 transistor or by turning on only a small portion of the sleep transistor at one time, in constrast to a conventional turn-on a1012 transistor which a1012 transistor turns on an entire portion of the sleep transistor with a rail to rail voltage.

The impact of the ground bounce caused by a power-mode transition is qualitatively characterized below. A1012 transistor understand ground bounce caused by the power mode transition, a simplified circuit model of FIG.

Ground bounce measurement is made by turning on the sleep transistor of the power gate structure The charge trapped in the capacitive loads and virtual a1012 transistor VGND rail during the standby period is a1012 transistor rapidly.

The power gate structure of FIG.

The logic circuit may contain any number of logic elements for performing a function of a semiconductor device or for storing data. The switching circuit includes a plurality of delay elements D0-D3. Each delay element corresponds to a single sleep transistor As the semiconductor device goes into an a1012 transistor state, the TURN-ON signal goes to a high logic level and will a1012 transistor delayed at each delay element as to a1012 transistor turn on each sleep transistoras can be seen from the timing diagram to the right of circuit The logic circuit will not enter the active mode until all sleep transistors are turned on.

The switching circuit is a shift register including a plurality of outputs Q0-Q3. Each output Q0-Q3 corresponds to a single sleep transistor As the semiconductor device goes into an active state, the TURN-ON signal goes to a high logic level and, at each subsequent clock cycle CLOCK, an output Q0-Q3 of the shift register will a1012 transistor on a corresponding sleep register, as can be seen from the timing diagram to the right of circuit The power gate of structure of FIG.

This will a1012 transistor a clock controlled discharge of the virtual ground line VGND by selectively charge sharing between the capacitor and the virtual ground line VGND or charge sharing between capacitor and the ground line GND by transistors and The logic circuit of may contain any number of logic elements for performing a function of a semiconductor device or for storing data.

As the semiconductor device goes into an active state, the TURN-ON signal goes to a high logic level and gradually charges the capacitor C10 until it reaches the threshold voltage of the sleep transistor turning the sleep transistor on.

The logic circuit will not enter the active mode until the sleep transistor is turned on.

The switching circuit is a1012 transistor of transistor with its drain tied to its gate, transistor with a first input control signal CTL1, transistorswith a second input control signal CTL2, and transistorswith the complement of the control signal CTL1.

When the semiconductor device goes into an active state, first control signal CTL1 a1012 transistor second control signal signal CTL2 simultaneously go to a low logic level.

A reference current, Iref, is set by the circuit and a ratio of this current is set in transistor This current is set to be sufficiently small as to not cause ground bounce and is maintained until the charge remaining in the function and storage block is sufficiently reduced to avoid ground bounce.
