摘要： An interface circuit for data transmission and the method thereof is described. The interface circuit includes a transmitter providing data through first data signals during the data periods corresponding to rising and falling edges of a clock signal, a transition detection unit selectively asserting a detection signal in response to the number of the first data signals having transitions between every two adjacent data periods, a transition reduction unit generating second data signals by outputting the inverted and non-inverted first data signals respectively when the detection signal is asserted and de-asserted, and a receiver restoring the data from the second data signals and the detection signal.

摘要： An operational amplifier circuit includes an analog driving circuitry and a digital driving circuitry. The analog driving circuitry is coupled to a load and drives the load according to an input signal. The digital driving circuitry includes a code comparator, a sourcing unit, and a sinking unit. The code comparator compares a reference code with codes corresponding to the input signal and generates a first control signal and a second control signal accordingly. The sourcing unit is coupled to the code comparator and the load, and sources a first current to the load according to the first control signal. The sinking unit is coupled to the code comparator and the load, and sinks a second current from the load according to the second control signal.
