    摘要: A representative memory device includes a cell array, at least one break cell that subdivides the cell array into bit cell arrays, and one or more power switches that are electrically coupled to the bit cell. In one embodiment, the break cell separates a connectivity of a first voltage and a second voltage between at least two bit cell arrays so that the bit cell arrays can be selectively coupled to either the first voltage or the second voltage using the power switches. The power switches control the connection of each separated bit cell array of the cell array to either the first voltage or second voltage.

    摘要: A method of operating a voltage regulator circuit includes generating a control signal by an amplifier of the voltage regulator circuit. The control signal is generated based on a reference signal at an inverting input of the amplifier and a feedback signal at a non-inverting input of the amplifier. A driving current flowing toward an output node of the voltage regulator circuit is generated by a driver responsive to the control signal, and the driver is coupled between a first power node and the output node. The feedback signal is generated responsive to a voltage level at the output node. A transistor, coupled between the output node and a second power node, is caused to operate in saturation mode during a period while the voltage regulator circuit is operating.

    摘要: A voltage regulator circuit with high accuracy and Power Supply Rejection Ratio (PSRR) is provided. In one embodiment, an op-amp with a voltage reference input to an inverting input has the first output connected to a PMOS transistor's gate. The PMOS transistor's source and drain are each connected to the power supply and the voltage regulator output. The voltage regulator output is connected to an NMOS transistor biased in saturation mode and a series of two resistors. The non-inverting input of the op-amp is connected in between the two resistors for the first feedback loop. The op-amp's second output is connected to the gate of the NMOS transistor through an AC-coupling capacitor for the second feedback loop. The op-amp's first output can be connected to the power supply voltage through a capacitor to further improve high frequency PSRR. In another embodiment, the role of PMOS and NMOS transistors is reversed.
