摘要： Multi-stage amplifiers, such as linear regulators, provide a constant output voltage subject to load transients. The multi-stage amplifier includes a first amplification stage which activates or deactivates a first output stage in response to an input voltage at an input node. The first output stage sources a current at an output node of the multi-stage amplifier from a high potential, when activated. Furthermore, the multi-stage amplifier has a second amplification stage to activate or to deactivate a second output stage in response to the input voltage at the input node. The second output stage sinks a current at the output node of the multi-stage amplifier to a low potential, when activated. The first amplification stage and the second amplification stage activate the first output stage and the second output stage in a mutually exclusive manner.

摘要： A regulator for providing a load current at a regulator output voltage to a load at an output of the regulator is described. The regulator has a differential input stage to provide a differential output voltage based on a reference voltage and based on the regulator output voltage. Furthermore, the regulator has an output driver to generate a control signal based on the differential output voltage. In addition, the regulator has a pass transistor to provide the load current in dependence of the control signal. The regulator also has clamping circuitry to sense an overvoltage indication which indicates that the pass transistor is being turned off. Furthermore, the clamping circuitry clamps the differential output voltage to a clamping voltage, if the overvoltage indication indicates that the pass transistor is being turned off.

摘要： A circuit includes a comparator that monitors a transient with respect to a predetermined threshold at the output of a voltage regulator and generates a compensation signal if the transient exceeds the predetermined threshold. A dynamic current pull-down block is triggered from the compensation signal of the comparator and operative with an output stage of the voltage regulator to mitigate the transient at the output of the voltage regulator by concurrently activating a plurality of current pull-down switches during the transient and sequentially deactivating each current pull-down switch of the plurality of current pull-down switches after its predetermined deactivation delay for each current pull-down switch.

摘要： During start-up of a circuit having a high voltage supply and a low voltage supply, a backup bias generator (BBG) is used to avoid burnout and exceeding a breakdown voltage. The high voltage supply is powered on before the low voltage supply. The BBG generates bias in response to the high voltage supply being powered on. Once the low voltage supply is powered on and is stable, the BBG is shut down so that it does not interfere with normal operation of the circuit. The circuit can be separated into high and low supply domains without breakdown issues during power start-up, allowing for power and area optimization.
