A voltage regulator for providing power to a system includes feedforward circuitry receiving a signal from the system indicating the current needed by the system, and the feedforward circuitry causes the voltage regulator to change the voltage regulator output current in response to the signal from the system.

Voltage regulator with adaptive feed-forward compensation for periodic loads

A programmable level shifter for providing upshifted control signals to an active matrix display based on logic-level control signals received from a timing controller. The programmable level shifter includes a programmable state machine, level-shifting output drivers, and a programming interface. The programmable state machine is configured to receive at least one control signal from a timing controller. The state machine generates, based on said at least one control signal, a plurality of outputs for driving gate drivers of the active matrix display. The level-shifting output drivers convert the plurality of outputs generated by the programmable state machine to a higher-magnitude voltage level. The programming interface facilitates the programming of aspects of the programmable state machine.

Programmable level shifter for LCD systems

An electronic device comprising a level shifter and a method. The level shifter includes an input adapted to receive an input signal switching between a low input voltage level and a high input voltage level and a first switch and a second switch coupled in series between a low output voltage supply and a high output voltage supply. An output is coupled to an interconnection node between the first and the second switch and is adapted to be coupled to a load. The first and second switches are controlled by the input signal. The level shifter further includes a third switch which is coupled between the interconnection node and an auxiliary voltage supply which has a voltage level between the low output voltage level and the high output voltage level.

Electronic device and method for providing a digital signal at a level shifter output

A level shifter for use in LCD display applications is provided which includes a group of separate channels each with a signal input and a signal output and with channel control circuitry supporting gate voltage shaping for improving image quality. The level shifter further has a number of flicker clock inputs. The channel control circuitry of each particular channel in the group comprises logic circuitry combining all of said flicker clock inputs with the signal input of the particular channel and signal inputs form other channels into a gate voltage shaping enable signal for the control circuitry of the particular channel. With this configuration it is possible to use the same level shifter IC with only one flicker clock signal for all phases, regardless of how many, without the need for an additional synchronization signal, or multiple flicker clock signals as is conventional. The level shifter automatically determines which input signal needs to be modified for the gate voltage shaping when the active portion of the flicker clock signal is detected.
