PAM-01C is a low noise and high gain charge sensitive preamplifier. It can be used as a key part for semiconductor detector, such as CZT and Si, and other detecting signal readout.
1. Charge Sensitive Pre-amplifier Chip Specifications Comparison
|Equivalent noise level||ENC:180e-||ENC:260e-|
|Falling edge time||250-400us||150-200us|
|Input charge range||<2000fc||<2941fc|
Added with bias high voltage, the CZT crystal would generate an inner electric field. An incident ray of X/γ-ray generate electron-hole pairs. Under the influence of the electric field, those pairs drifting to two poles. And then induced charges generated in relative poles. Then the low noise charge sensitive preamplifier circuit converts those charges into exponential decay pulse signal.
