摘要： A charge/discharge protection circuit protects a battery from inadvertent shorting on a charger node that can connect to a charger or to a power supply of a portable electronic device. A single n-channel power transistor has a gate that controls a channel between the battery and the charger node. The gate is connected to the charger node by a gate-coupling transistor to turn off the power transistor, providing battery isolation. The gate is driven by a voltage-boosted clock through a switch activated by an enable signal. The enable signal also activates a grounding transistor to ground a gate of the gate-coupling transistor. A comparator compares voltages of the charger and battery nodes, and the compare output is latched to generate the enable signal. An inverse enable signal activates a second switch that drives the voltage-boosted clock to the gate of the gate-coupling transistor to turn off the power transistor.

摘要： An electro-static-discharge (ESD) protection circuit protects core transistors. An internal node to the gate of an n-channel output transistor connects to the drain of an n-channel gate-grounding transistor to ground. The gate of the gate-grounding transistor is a coupled-gate node that is coupled by an ESD coupling capacitor to the output and to ground by an n-channel disabling transistor and a leaker resistor. The gate of the n-channel disabling transistor is connected to power and disables the ESD protection circuit when powered. An ESD pulse applied to the output is coupled through the ESD coupling capacitor to pulse high the coupled-gate node and turn on the gate-grounding transistor to ground the gate of the n-channel output transistor, which breaks down to shunt ESD current. The ESD pulse is prevented from coupling through a parasitic Miller capacitor of the n-channel output transistor by the gate-grounding transistor.

摘要： A bandgap reference voltage generator has a first stage that generates a first current that is complementary-to-absolute-temperature (Ictat) and a second stage that generates a current that is proportional-to-absolute-temperature (Iptat). The Ictat and Iptat currents are both forced through a summing resistor to generate a voltage that is relatively independent of temperature, since the Ictat and Iptat currents cancel out each other's temperature dependencies. A PMOS output transistor drives current to an output load to maintain the load at the reference voltage. An op amp drives the gate of the PMOS output transistor and has inputs connected to emitters of PNP transistors in the second stage. A series of resistors generate the reference voltage between the PMOS output transistor and ground and drives bases of the PNP transistors and includes the summing resistor. Parasitic PNP transistors in an all-CMOS process are used. The generator operates with a 1-volt power supply.

摘要： An Analog-to-Digital Converter (ADC) has a Successive-Approximation-Register (SAR) driving a digital-to-analog converter (DAC) that generates an analog voltage compared to an input voltage by a series of stages. The last stage feeds a compare signal to the SAR. Each stage has a dual-input differential amplifier that operates as a unity gain op amp during an auto-zeroing phase and as a high-speed low-gain amplifier during an amplifying phase. The dual-input differential amplifier has two pairs of differential inputs. A secondary pair has an offset-storing capacitor across it, and connects to the output pair through feedback switches during auto-zeroing. A primary pair connects to stage inputs through input switches during the amplifying phase. Since two pairs of differential inputs are provided to the dual-input differential amplifier, the offset capacitor is completely isolated from the input pair. The current sink in the dual-input differential amplifier is adjusted higher during the amplifying period.

摘要： A fly-back AC-DC power converter has a constant-current control loop that senses the primary output current in a transformer to control the secondary output without an expensive opto-isolator. A primary-side control circuit can use either a Quasi-Resonant (QR) or a Pulse-Width-Modulation (PWM) control loop to switch primary current through the transformer on and off. A feedback voltage is compared to a primary-side voltage sensed from the primary current loop to turn the switch on and off. A multiplier loop generates the feedback voltage using a multiplier. A level-shift inverter and a low-pass filter act as the multiplier by multiplying an off duty cycle of the switch by the feedback voltage to generate a filtered voltage. A high-gain error amp compares the filtered voltage to a reference voltage to generate the feedback voltage. The multiplier produces a simple relationship between the secondary current and the reference voltage, yielding simplified current control.
