Query: Application of the DRS4 Chip for GHz Waveform Digitizing Circuit   At present, fast waveform digitizing circuit is more and more employed in
modern physics experiments for processing the signals from an array detector. A
new fast waveform sampling digitizing circuit developed by us is presented in
this paper. Different with the traditional waveform digitizing circuit
constructed with analog to digital converter(ADC) or time to digital
converter(TDC), it is developed based on domino ring sampler(DRS), a switched
capacitor array(SCA) chip. A DRS4 chip is used as a core device in our circuit,
which has a fast sampling rate up to five gigabit samples per second (GSPS).
The circuit has advantages of high resolution, low cost, low power dissipation,
high channel density and small size. The quite satisfactory results are
acquired by the preliminary performance test of this circuit board. Eight
channels can be provided by one board, which has a 1-volt input dynamic range
for each channel. The circuit linearity is better than 0.1%, the noise is less
than 0.5 mV (root mean square, RMS), and its time resolution is about 50ps. The
several boards can be cascaded to construct a multi-board system. The good
performances make the circuit board to be used not only for physics
experiments, but also for other applications.
