Abstract :
This paper presents an ultra-fast CMOS Data- Acquisition system. It has been developed predominately for use in Optical Scanning Acoustic Microscopy, and it is also applicable in RF transceiver systems. The key modules of this system include a sub- sampling sample-and-hold amplifier, and a pulse generator, which is based on a 2.6 GHz PLL with quadrature outputs and provides control signals for the SHA. The DAQ system is implemented in a standard 0.35 μm CMOS process, and achieves 10.2 G Sample/s sampling rate for the 80 MHz periodic laser input.
