    摘要： An electronic device includes a transistor having a body and a body biasing circuit. The body biasing circuit includes a threshold estimator circuit to estimate a threshold voltage of the transistor and a comparison circuit to compare the threshold voltage of the transistor to a reference threshold voltage and to generate a comparison signal based thereupon. A bias adjust circuit generates a body biasing voltage that biases the body of the transistor as a function of the comparison signal, the body biasing voltage being a voltage that, when applied to the body of the transistor, adjusts the threshold voltage thereof to be equal to the reference threshold voltage.

    摘要： A generator circuit is coupled to apply a control signal to the gate terminal of a power transistor driving an output node. A reference voltage is generated having a first voltage value as the reference for the control signal and having a second, higher, voltage value for use in stress testing. A clamping circuit is provided between the reference voltage and the power transistor gate to function in two modes. In one mode, the clamping circuit applies a first clamp voltage to clamp the voltage at the gate of the power transistor when the generator circuit is applying the control signal. In another mode, the clamping circuit applies a second, higher, clamp voltage to clamp the gate of the power transistor during gate stress testing.

    摘要： A class D amplifier receives and amplifies a differential analog signal which is then differentially integrated. Two pulse width modulators generate pulse signals corresponding to the differentially integrated analog signal and two power units generate output pulse signals. The outputs the power units are coupled to input terminals of integrators via a resistor feedback network. An analog output unit converts the pulse signals to an output analog signal. The differential integration circuitry implements a soft transition between mute/un-mute. In mute, the integrator output is fixed. During the soft transition, the PWM outputs change slowly from a fixed 50% duty cycle to a final value to ensure that no pop noise is present in the output as a result of mode change.

    摘要： A Class-D amplifier includes a pre-amplifier having an input configured to receive an amplifier reference voltage signal which is ramped at start-up at a fast rate. An integrator has a first input configured to receive an input signal from the pre-amplifier and a second input configured to receive an integrator reference voltage signal which is ramped at start-up at a slower rate. A modulator has an input coupled to an output of the integrator. The modulator generates a pulse width modulated output signal. Operation of the Class-D amplifier is controlled at start-up by applying a slow ramped signal as the integrator reference voltage signal and a fast ramped signal as the amplifier reference voltage so that the pulse width modulated output signal exhibits an increasing change in duty cycle in response to an increasing voltage of the integrator reference voltage signal, and no “pop” is introduced at start-up.
