A p-channel Junction Field Effect Transistor on a fully depleted high
ohmic silicon substrate (DEPJFET) has been used as unit cell for pixel
detectors. The most important features of this structure are the inte
rnal charge amplification, the low power consumption and the low detec
tor capacitance leading to a high signal to noise ratio. Two different
prototype designs, featuring pulsed or continuous reset, have been fa
bricated and tested. Both have been characterized with respect to thei
r signal performance and noise behavior.
