摘要： A configurable switched capacitor block includes a switched-capacitor (SC) sampling circuit, a fully differential amplifier, an SC feedback circuit, and a comparator. The SC sampling circuit is coupled to receive an input signal and to selectively generate a sampled signal to a differential input of the amplifier. The SC feedback circuit is coupled between the differential inputs and the differential outputs of the amplifier to selectively control a feedback of the amplifier. The comparator is coupled to the differential outputs of the amplifier to generate an output signal. The configurable switched capacitor block has multiple modes of operation which are selectable by programming the SC sampling circuit and the SC feedback circuit.

摘要： Embodiments of the invention relate to a method and apparatus to reduce power consumption in a passive matrix LCD driver circuit by using a plurality of drive buffers and active power management of sub-blocks in the passive matrix LCD drive circuit. Each drive buffer may operate in a first phase, which may include a high-drive mode to drive an LCD voltage to a threshold voltage level and a low-drive mode to modify the LCD voltage to approximate an input voltage of the drive buffer, and to maintain a constant LCD voltage level. The low-drive buffer consumes less current than the high-drive buffer, thus reducing power consumption. The drive buffer may also operate in a second phase, also a no-drive mode, in which the drive buffer and the bias voltage generator may be completely turned off, to further reduce power consumption. The drive buffer may be used to drive capacitive loads, as well as partially-resistive loads and inductive loads.

摘要： A method and system dynamically controlling microcontroller power. In one embodiment, the method and system configures a microcontroller power state, senses its condition, and determines its suitability status, communicates that status between a POR circuit and a processor, controls certain microcontroller functions accordingly, and dynamically programs power related functions. This is enabled, in one embodiment, by dynamic interaction between the POR circuit and the processor. Microcontroller power status is ascertained, and a corresponding optimal power state determined. Optimal values for programmable independent multiples of a supply voltage is programmatically calculated and set, dynamically adjusting microcontroller power states. In one embodiment, the optimal values are communicated to a scaler in the POR circuit by the processor, and registered within a multiplexer/register matrix within the scaler. The processor commands the matrix to change programmable independent multiples of supply voltage to correspond with the optimal values, and monitors corresponding action and power status.
