摘要： An apparatus including cascaded amplification stages adapted to be biased by a common DC current to generate an amplified output signal from an input signal. A first amplification stage includes a routing network to substantially double an input voltage signal, and a first transconductance gain stage to generate a first current signal from the input voltage signal. A second amplification stage includes a resonator to convert the first current signal into a second voltage signal, and a second transconductance gain stage to generate a second current signal from the first current signal. A third amplification stage includes a current gain stage to generate a third current signal from the second current signal, and a load through which the third current signal flows to generate the output signal.

摘要： An apparatus is disclosed for generating an output signal (e.g., a defined pulse), including a power or current calibration feature. The apparatus comprises a current source adapted to generate a first current to produce the output signal, a current sampling module adapted to generate a second current as a function of (e.g., substantially proportional or equal to) the first current, a reference current module (e.g., a bandgap current source) adapted to generate a third current, and a calibration module adapted to calibrate the first current based on the second and third currents. The current source comprises a plurality of selectable current paths. The current sampling module comprises a replica of at least a portion of one or more current paths of the current source. The calibration module may perform a calibration in response to a defined time, an environment parameter (temperature, voltage, pulse repetition frequency, amplitude requirement change, etc.), or the output signal not being generated.
