US 10,541,679 B1 · Pulse amplifier

Abstract

Various aspects of amplifying amplitude of a pulse are disclosed herein. In sonic embodiments, a device includes driver circuitry that receives an input pulse swinging or transitioning between a first reference voltage and a second reference voltage higher than the first reference voltage, In some embodiments, the driver circuitry generates a driving pulse swinging between a third reference voltage and the second reference voltage according to the input pulse, where the third reference voltage is between the first reference voltage and the second reference voltage. In some embodiments, the device further includes a transistor coupled to the driver circuitry. In some embodiments, the transistor outputs an output pulse swinging between the first reference voltage and an output voltage according to the driving pulse from the driver circuitry, where the output voltage is higher than the second reference voltage.
