Abstract
A High-speed Current Mode Analog to Digital Converter is disclosed. The ADC is high-speed, yet is manufacturable at a relatively low cost. The device processes an analog signal through a plurality of successive approximation ADC subcircuits cooperatively arranged to operate in parallel, time-interleaved fashion. The ADC subcircuits operate in current mode rather than voltage mode in order to further accelerate their operations and provide lower cost. Finally, the SDC subcircuits each employ a novel current mode digital-to-analog converter.
