This is a video about high speed analog to digital converter. Analog to digital converter (ADC) is a device that is used to convert an analog signal into digital. For example femtocharge, it implements the gain trough capacitor scaling, each pipeline stage has its input. Reducing the capacitance will increase the voltage. Here is the video :

The femtocharge has some advantages such as it is a complete and easy to use system, fast, “datasheet” display, low cost and has adjustable gain, skew, offset, configurable output and multiple power down modes. The high speed ADCs are used in many application like data acquisition, medical imaging instumentation and test, high definition imaging/video, wireles infrastructure, SDR software defined radio, communication and military cable head end equipment. For example the used of high speed ADC in data acqusition are USB digitizer and USB osciloscope ATE, etc. For medical imaging, PET scan and MRI/CT scane.
