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： Apparatus for generating a first signal (e.g., a pulse) including a current source adapted to generate a current based on a second signal that defines an amplitude of the current and a third signal that defines the timing of an amplitude change of the current, and an impedance element through which the current flows to generate the first signal. The impedance element may comprise a resonator having a resonant frequency approximate the center of the first signal frequency spectrum. An LO may be used to generate the third signal to control the timing of the amplitude change of the current. A detector may enable the current source in response to detecting a defined steady-state condition of the LO clock signal, and may disable the current source in response to the completion of the first signal. A controller may generate the second signal to control the current amplitude so as to perform power control and/or other functions.

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.
