Abstract: A switching-capacitor regulator with a charge injection mode for a high loading current is used to generate an output voltage at an output node, where the switching-capacitor regulator includes a storage capacitor, a switch module, a current source and a control unit. The switch module is coupled between the storage capacitor, a first supply voltage, a second supply voltage and the output node. The current source is coupled to the output node, and is used for selectively providing a current to the output node.

Abstract: A low-dropout voltage regulator apparatus includes a voltage source circuit, an error amplifier, an output transistor, a resistor-capacitor circuit, a detection circuit, and a current adjusting circuit. The voltage source circuit generates a reference voltage signal and at least one threshold voltage signal. The error amplifier receives the reference voltage signal and a feedback voltage signal to generate an output control signal. The output transistor provides an output current for the output terminal according to the output control signal. The resistor-capacitor circuit generates the feedback voltage signal using voltage dividing according to a voltage corresponding to the output current. The detection circuit compares at least one threshold voltage signal with the output voltage to generate at least one control voltage signal.

Abstract: A circuitry for measuring a time interval with ring oscillator has a ring oscillator formed by a plurality of delay switching units, a counter and an encoder. Wherein, the ring oscillator generates a plurality of oscillating signals when receives a pulse signal used to turn on or turn off the ring oscillator. The counter can count the numbers of the oscillating signal during an active period of the pulse signal to generate a counting value. In addition, the encoder encodes the oscillation signals generated by a plurality of delay switching unit with a certain interval of delay time. Therefore, when the pulse signal is disabled to lead to turn off the ring oscillator, one can obtain the time interval of the pulse signal based on the encode data and the counting value.
