A voltage-to-digital converting device includes a first voltage-to-time converter outputting a first delay clock having a first time delay relative to a reference clock in response to an input voltage, and a second voltage-to-time converter outputting a second delay clock having a second time delay relative to the reference clock in response to a feedback voltage. The first and second time delays correspond respectively to the input and feedback voltages. A time-to-digital converting circuit receives the first and second delay clocks from the first and second voltage-to-time converters, compares phases of the first and second delay clocks, generates the feedback voltage based on result of phase comparison made thereby, and outputs a digital signal upon detecting that the phases of the first and second delay clocks are in-phase.

A method of fabricating a vertical thin film transistor (vertical TFT) is disclosed, wherein a shadow mask is used to fabricate the TFT device in vertical structure. First, a metal layer is formed, which serves as ribs and a gate layer. Next, a shadow mask is disposed on the gate layer. Afterwards, the shadow mask is used as a mask to form a source layer, an organic semiconductor layer and a drain layer. Thus, the process is simplified. Since no photolithography process is required, and therefore damage of the organic semiconductor layer is avoided and a vertical TFT with desired electrical characteristics may be obtained.

The invention provides a continuous-time delta sigma modulator. In one embodiment, the continuous-time delta sigma modulator comprises a series of integrators, a quantizer, and a loop delay compensation circuit. The integrators are coupled in series and generate an analog output signal according to an analog input signal. The quantizer quantizes the analog output signal according to a reference voltage to generate a digital output signal as the output of the continuous-time delta sigma modulator. The loop delay compensation circuit adjusts the reference voltage of the quantizer according to the digital output signal to compensate the continuous-time delta sigma modulator for a loop delay.

摘要:
Calibration of a phase locked loop and applications thereof within a radio frequency integrated circuit begins by determining an intersection of an up current and down current produced by a charge pump within the phase locked loop. The RFIC then determines a reference voltage corresponding to the intersection, which varies from an ideal voltage of VDD/2 based on process variations. The RFIC then offsets a control voltage to the voltage control oscillator (VCO) of the phase locked loop based on the reference voltage. Accordingly, by determining the offset of the actual intersection from the ideal intersection, the control voltage to the VCO may be adjusted thereby calibrating the phase locked loop for more linear performance.
摘要:
A radio transceiver includes a charge pump formed within a local oscillator that adjusts a voltage input to a voltage-controlled oscillator in a manner that flattens a response curve for small changes in voltage due to a variety of effects including channel length modulation. Thus, a local oscillation tends to provide a greater degree of stability. More specifically, the charge pump of the transceiver includes a pair of feedback circuits that source an additional amount of current into a filter to slightly increase a voltage input to the voltage-controlled oscillator in response to small upward changes in output voltage levels (input with respect to the voltage-controlled oscillator). Similarly, when the output voltage level drops slightly, a second feedback circuit causes a small amount of current to be sinked from the output node thereby slightly decreasing the input voltage to the voltage-controlled oscillator. Thus, the inventive charge pump produces better matching between IUP and IDOWN thus operating to produce a response curve that tends to be flatter in response to small voltage changes due to circuit conditions.
