摘要： A power supply supervisor having a line voltage detector is used to monitor a power supply. A peak detector detects the line voltage by measuring the PWM switching signal in the secondary of the transformer. A logic circuit couples to the peak detector and the under-voltage detector, etc. to generate a power good (PG) signal when the power supply outputs meet the specifications. The logic circuit outputs a FAIL signal to turn off the power supply when an abnormal situation, such as over-voltage, occurs. Furthermore, when AC power is lost or turned off, the logic circuit detects a low line voltage and generates a power-down-warning PG signal before the output voltages are disabled. When an abnormal situation occurs before the low line voltage is detected, the logic circuit latches the power supply in a power off state. If the abnormal situation occurs after the low line voltage is detected, the logic circuit turns off the power outputs, but disables the latch function. In the meantime, a time delay circuit is applied to postpone the power off status, in which the time delay limits the duty cycle of power outputs and protects the power supply from over-stress damage.

摘要： An analog to digital video converter is made of a differential correlated double sampling (DCDS) module, a DC bias circuit, an adjustment module and an analog-to-digital converter. The DCDS module samples a red, a green, and a blue analog signal respectively with a delay time, and then selects one of the sampled signals for outputting. The DC bias circuit is connected to the DCDS module for performing an analog addition to the output signal of the DCDS module. The adjustment module converts the digital adjustment data to an analog adjustable reference voltage. The analog-to-digital converter is connected to the output of the DC bias circuit and the adjustment module. By referring the adjustable reference voltage, the analog-to-digital converter converts the analog input signal to a digital output signal. Therefore, the analog input signal is equivalently adjusted by scaling the adjustable reference voltage.

摘要： An electrostatic discharge (ESD) device has a parasitic SCR structure and a controllable trigger voltage. The controllable trigger voltage of the ESD device is achieved by modulating a distance between an edge of a lightly doped well and an edge of a heavily doped region located at two ends of the lightly doped well. Since the distance and the trigger voltage are linearly proportional, the trigger voltage can be set to a specific value from a minimum value to a maximum value.

摘要： The present invention discloses a switching control circuit for a primary-side controlled power converter. A voltage-waveform detector produces a voltage-feedback signal and a discharge-time signal. A current-waveform detector generates a current-waveform signal by measuring a primary-side switching current. An integrator generates a current-feedback signal by integrating the current-waveform signal with the discharge time. A time constant of the integrator is correlated with the switching frequency, thus the current-feedback signal is proportional to an output current of the power converter. A PWM circuit controls the pulse width of the switching signal in response to the outputs of a voltage-loop error amplifier and a current-loop error amplifier. The output voltage and the maximum output current of the power converter are therefore regulated.

摘要： The invention presents a switching control circuit for a primary-side-controlled power converter. A pattern generator produces a digital pattern to control a programmable capacitor that is connected to an oscillator, which produces frequency hopping to reduce the EMI. A voltage-waveform detector produces a voltage-feedback signal and a discharge-time signal by multi-sampling a voltage signal of a transformer. A current-waveform detector and an integrator generate a feedback signal. The integration of a current-waveform signal with a timing signal generates the average-current signal. Time constant of the integrator is correlated to the switching frequency. The oscillator generates the timing signal and a pulse signal in response to the output of a current-loop error amplifier. A PWM circuit generates the switching signal in response to the pulse signal and the output of a voltage-loop error amplifier for switching the switching device and regulating the output of the power converter.

To form an equivalent SCR structure, the ESD device includes a plurality of N+ regions and a plurality of P+ regions formed inside an N-well.

摘要： The switched charge multiplier-divider according to the present invention is constructed of CMOS devices. Capacitor charge theory is employed to implement the circuit of the switched charge multiplier-divider. The switched charge multiplier-divider includes an output capacitor and controls the voltage across the output capacitor, so that it is proportional to the product of the charge current and the charge-time interval. The switched charge multiplier-divider is ideal for use in the power factor correction (PFC) of switching mode power supplies. Potentially, it can also be applied to automatic gain control (AGC) circuits.
