    摘要: A PWM controller has a line voltage input that allows using an input resistor for both start-up and power-limit compensation, thus saving the power consumption, easing the PCB layout, and shrinking the power supply size. In the integrated circuit, a mirrored-resistor used for the power limit compensation is composed of a mirror MOSFET, which is associated with an op amplifier, a constant voltage and a constant current to provide a precise resistance. Thus, by properly selecting the value of the input resistor, an identical output power limit for low line and high line voltage input can be achieved.

    摘要: A Chinese abacus adder is disclosed. The Chinese abacus adder includes a B/A (binary to abacus) circuit, a P/A (parallel addition) circuit and a T/B (thermometric to binary) circuit. The Chinese abacus adder has a multiple radix calculating structure, which could reduce power consumption of the system and lower the calculation delay time.
