Charge transfer circuit for compact modulators
The present disclosure provides a current generation circuit. In one aspect, the circuit includes a current source transistor and a current sink transistor connected to the current source transistor in series, with respective sources of the current source and sink transistors being connected with each other at a common node. A voltage difference between respective gates of the current source and sink transistors defines a current value flowing through the series, the voltage difference being variable such that the current value is either time-dependent or time-independent. Respective drains of the current source and sink transistors provide a high resistance output necessary to provide a current source or sink function thereby rejecting influence of drain variation or error on the current value.
High-speed level shifter
Embodiments disclosed herein relate to level shifters of a memory device. Specifically, the level shifters include a first series arrangement of transistors to offset a first transistor. The level shifters also include a second series arrangement of transistors to offset a second transistor. The first series arrangement of transistors is opposite the second series arrangement of transistors. The output of the first series arrangement of transistors is coupled to a first node and selectively couples the first node to a first voltage based on an input signal. The output of the second series arrangement of transistors is coupled to a second node and couples the second node to the first voltage based on an input signal. The first node and the second node are coupled to the first voltage at different times. The series arrangements of transistors enables faster level shifting over conventional level shifters.

ISOLATED SWITCHED-MODE POWER CONVERTER HAVING SECONDARY-SIDE RECTIFIED VOLTAGE SENSING
An isolated switched-mode power converter converts power from an input source into power for an output load. A digital controller senses a secondary-side voltage, such as a rectified voltage, of the power converter. The secondary-side voltage is divided down using a high-impedance voltage divider. The resultant divided-down voltage is provided to a voltage sensor within the digital controller. The voltage sensor level shifts the provided voltage, and buffers the resulting level-shifted voltage. The buffered, level-shifted voltage is provided to a tracking analog-to-digital converter (ADC) for digitization. The buffered signal provided to the tracking ADC has a high current capability, such that the voltage input to the tracking ADC may quickly converge before the tracking ADC outputs a digital value for the sensed secondary-side voltage.
METHOD AND ARRANGEMENT FOR ENSURING VALID DATA AT A SECOND STAGE OF A DIGITAL REGISTER CIRCUIT
A digital value obtained from a preceding circuit element is temporarily stored and made available for a subsequent circuit element at a controlled moment of time. The digital value is received through a data input. A triggering signal is also received, a triggering edge of which defines an allowable time limit before which a digital value must be available at said data input to become available for said subsequent circuit element. Between first and second pulse-enabled subregister stages, an internal digital value from the first pulse-enabled subregister stage and information of the changing moment of said digital value at the data input in relation to said allowable time limit are used to ensure passing a valid internal digital value to the second pulse-enabled subregister stage. Said second pulse-enabled subregister stage makes said valid internal digital value available for said subsequent circuit element. A timing event observation signal is output as an indicator of said digital value at said data input having changed within a time window that begins at said allowable time limit and is shorter than one cycle of said triggering signal.
