摘要： A reference circuit for providing a precision voltage and a precision current includes a bandgap voltage reference circuit, a positive temperature coefficient calibrating circuit, a threshold voltage superposing circuit and precision current generator interconnected in cascade. From the bandgap voltage reference circuit, a bandgap voltage is outputted as the precision voltage, and a PTAT current is outputted to the positive temperature coefficient calibrating circuit along with the bandgap voltage for generating a PTAT voltage. In response to the PTAT voltage from the positive temperature coefficient calibrating circuit, the threshold voltage superposing circuit generates a first voltage which is equal to the PTAT voltage plus a threshold voltage. Then the precision current generator outputs a reference current as the precision current in response to the first voltage.

摘要： 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.

摘要： An apparatus and a method for frequency locking are provided. The apparatus includes a phase-locked loop (PLL), a local clock generator, a data buffer unit and a control unit. The PLL locks the phase and the frequency of a radio frequency signal to generate a recovery clock signal and received data. The data buffer unit writes the received data into an elastic buffer of the data buffer unit according to the frequency of the recovery clock signal, and reads the received data from the elastic buffer according to the frequency of a local clock signal generated by the local clock generator. The control unit obtains a write-in address and a read-out address in the elastic buffer, and sends a control signal to the local clock generator for adjusting the frequency of the local clock signal according to relationship between the write-in address and the read-out address.
