The present invention provides a digital receiver configured to demodulate or decode a pulse-width modulated (PWM) signal from a transmitter. The receiver digitally demodulates or decodes the pulse-width modulated signal so as to obtain (binary) values of data modulated on pulse periods of the pulse-width modulated signal. The digital receiver includes multiple delay cells coupled to one another in series and a sampling circuit coupled to one of the delay cells. A sequential coupling of the delay cells composes a signal path, and each of the delay cells is designed to provide a corresponding delay to a corresponding input signal propagating along the signal path so as to generate a delayed signal as its output.

Method for portable device processing data based on clock extracted from data from host

The clock generation method contains the following steps. In a pulse recognition step, an input pulse signal is first filtered to remove a shorter signal. Then, a width digitization calculation is conducted on the remaining pulse signal. Based on the width digitization calculation, a signal is recorded and a period of the recorded signal is determined. The value of the period is delivered to a gain module. In a step for verifying the input value to D/A converter, two values are input to a D/A converter from the gain module, and the output from the D/A converter is delivered to an oscillator. The gain module determines a desired input value from the gain module to the D/A converter. In a pulse generation step, the gain module inputs the desired input value to the D/A converter which in turn delivers to the oscillator for the generation of a corresponding clock.

A reference current generator circuit suitable for low-voltage applications is provided. The generator circuit is fabricated in a chip for generating a precise reference current based on a precise reference voltage and a precise external resistor. The generator circuit provides an equivalent resistance coupled in parallel with the external resistor to provide resistance compensation and reduce the impedance of seeing into the chip from a chip pad. In addition to the resistance compensation, only moderate capacitance compensation is required to enhance the phase margin of the generator circuit, so as to achieve a stable loop. Therefore, chip area and cost can be reduced in low-voltage applications. In addition, the generator circuit reproduces the reference current generated by the external resistor by utilizing current mirrors, so as to eliminate the effect on currents caused by parallel coupling of the equivalent resistance and the external resistor.

When the digital signal has a first logic state, the first switch is turned off, and the second switch is turned on. When the digital signal has a second logic state, the first switch is turned on, and the second switch is turned off.
