Abstract:
PURPOSE: A clock data recovery circuit using a dual interpolation method and a method thereof are provided to lower the frequencies of a clock generator by keeping the number of supply clocks as many as that of a 1/2 rate frequency method using a double interpolation method. CONSTITUTION: A clock generator(170) generates a first clock with the 1/4 frequency of the rate of the received data. A clock generator generates a second clock having the 90 degrees of a phase difference with the phase of the first clock. A first phase interpolator(110) performs a first phase interpolation by transferring the first and the second clock from the clock generator to an optimum sampling position for data. A second phase interpolator(120) additionally generates a third clock and a fourth clock with phase difference of each 45 degrees between the first clock and the second clock interpolated by the first phase interpolator. A phase detector generates eight UP signals and eight DOWN signals through the phase comparison of the first clock to the fourth clock.
Abstract:
A power-on-reset circuit is provided to generate a reset signal, which is not sensitive to a PVT(Process Voltage Temperature) variation, by generating reset signals during both power-on and power-off processes. A power-on-reset circuit includes a voltage divider(100), a temperature compensator(110), and a reset signal generator(120). The voltage divider divides a source voltage. The temperature compensator outputs a voltage, which is inversely proportional to a magnitude of the output voltage from the voltage divider. The reset signal generator outputs a reset signal according to the output voltage from the temperature compensator. The voltage divider includes a first PMOS(Positive Metal Oxide Semiconductor) transistor and a first NMOS(Negative Metal Oxide Semiconductor) transistor. A gate of the first PMOS transistor is connected to a connection node between the first PMOS transistor and the first NMOS transistor and operates as an output terminal of the voltage divider. A gate of the first NMOS transistor is connected to a power supply.
