    摘要： A phase-locked loop (PLL) is arranged to receive high-pass data at a first input and low-pass data at a second input. A first digital input is coupled to a primary path through a digital-to-analog converter (DAC) and a second digital input is coupled to a feedback path of the PLL. The controller provides the first input and the second input during a calibration procedure. The controller adjusts first and second control inputs in an attempt to keep the input voltage to a voltage-controlled oscillator (VCO) in the PLL constant while determining the gain of the VCO in Hz/LSB.

    摘要： A loop filter capable of controlling a charge sharing point in time, a phase locked loop, and a method of operating the loop filter are provided. The loop filter includes a duty control unit and a variable capacitor unit. The duty control unit generates a duty control clock signal of which an activation section is shorter than an inactivation section, by controlling a duty of an input clock signal. The variable capacitor unit is charged by an input current and has a capacitance that varies according to the duty control clock signal. The variable capacitor unit may include a switch, a first capacitor, and a second capacitor. The switch is turned on or off in response to the duty control clock signal. The first capacitor is serially connected to the switch and charged by the input current when the switch is turned on. The second capacitor is connected in parallel to the switch and the first capacitor and charged by the input current.

    摘要： For sensing a target temperature, first and second temperature detectors generate first and second delay signals having negative and positive delay changes with temperature. A comparator senses the target temperature from the first and second delay signals such as by activating an output signal when the temperature is at least the target temperature.
