PETRIC. A positron emission tomography readout integrated circuit
We present architecture, critical design issues and performance measurements of PETRIC, a 64-channel mixed signal front-end integrated circuit (IC) for reading out photodiode (PD) array coupled with LSO scintillator crystals for a medical imaging application (PET). Each channel consists of a low noi...

| description | We present architecture, critical design issues and performance measurements of PETRIC, a 64-channel mixed signal front-end integrated circuit (IC) for reading out photodiode (PD) array coupled with LSO scintillator crystals for a medical imaging application (PET). Each channel consists of a low noise charge sensitive pre-amplifier (CSA), an RC-CR pulse shaper and a winner-take-all (WTA) multiplexer that selects the channel with the largest input signal. Triggered by an external timing signal, a switch opens and a capacitor stores the peak voltage of the winner channel. The shaper rise and fall times are adjustable by means of external current inputs over a continuous range of 0.5 /spl mu/s to 10 /spl mu/s. Power consumption is 5.4 mW per channel, measured equivalent noise charge (ENC) at 1 /spl mu/s peaking time, zero leakage current is 33 rms electrons plus 7.3 rms electrons per pF of input capacitance. Design is fabricated in 0.5 /spl mu/m 3.3 V CMOS technology. |
