摘要： An embodiment of a variable stage charge pump includes a plurality of pump stages. Each stage is configured to generate an intermediate boosted output voltage. A pump stage selector selects the number of charge pump stages to be coupled between an input and output terminal of the variable stage charge pump. The pump stage selector may control a plurality of switches to select the number of stages. For example, two stages maybe coupled in parallel and the parallel combination coupled in series to a third stage, resulting in a two stage charge pump. For a three stage charge pump, all three stages are coupled in series.

摘要： Some embodiments include apparatus and methods having a first switch, a second switch, and a circuit coupled to the first and second switches. The first switch may be configured to switch between an on-state and an off-state based on a value of a first current flowing through a number of resistors and a diode coupled in series with the resistors. The second switch may be configured to switch between the on-state and the off-state based on a value of a second current on a circuit path. The second current is a function of a voltage at a node between two of the resistors and a resistance of the circuit path. The circuit may be configured to provide a temperature reading based on the number of times the first switch or the second switch switches between the on-state and the off-state during a time interval.

A pull up transistor and a pull down transistor are respectively serially coupled to first and second switches for alternatingly respectively switching additional pull up and pull down current into the pull up output current and the pull down output current. A comparator controls the additional pull up and pull down currents in response to a comparison of a summed output voltage and a reference voltage.

摘要： An input buffer receiver circuit for electronic devices (e.g., memory chips) to receive and process reduced-swing and high bandwidth inputs to obtain “buffered” output signals therefrom with symmetrical rising and falling delays, and without additional current dissipation over previous receiver circuits, is disclosed. The receiver circuit may include two stages of differential amplifier pairs (i.e., a total of 4 separated differential amplifiers). The differential amplifiers in the first stage convert the single-ended input signal to a full-differential signal, which is then converted back to a single-ended output signal by the differential amplifier pair in the second stage. The output of a P-diff first stage may be connected to the input of an N-diff second stage and the output of an N-diff first stage may be connected to the input of a P-diff second stage thereby creating a “cross” coupled structure. Various current saving and biasing methods may also be employed to keep the operating current the same or lower than the previous receiver circuit designs. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
