摘要： The present disclosure introduces a simple method and apparatus for a Class-D amplification and Pulse Width Modulation (PWM) of an input signal, such as a voice signal. The proposed circuits do not require reference input signals such as triangular signals; rather, the combination of the circuits' self-oscillating device arrangements and the delay elements performs pulse width modulation at higher frequencies while producing less noise. Among other advantages, these circuits offer shorter response time, less distortion, better power supply ripple rejection, larger negative feedback, and simpler construction. The recommended Class-D amplifiers can be used with speakers and can have single-ended or differential input.

摘要： A full wave sense amplifier for sensing a periodic current flowing through a discharge lamp is disclosed. The full wave sense amplifier comprises a means for sensing the positive going portion of the periodic current. The amplifier also includes means for sensing the negative going portion of the periodic current. Finally, a means for combining the negative going portion and the positive going portion into a current flow signal is provided.

摘要： An integrated circuit driver is disclosed. The driver comprises a high side transistor and low side transistor connected in series. The output of the driver is taken from the source of the high side transistor and the drain of the low side transistor. A bootstrap contact pad is connected to the output node. A bootstrap package pin is connected to the bootstrap pad by a dedicated bootstrap bond wire. Connected to the bootstrap package pin is a bootstrap capacitor that is also connected to a high side gate drive that selectively controls the high side transistor.
