Title: X-ray detection circuit in semiconductor integrated circuit designing
Inventor: MORIYA ATSUSHI
IPC: A61B6/03
Filed: 1987-01-23
Abstract: PURPOSE:To achieve a higher quality of picture of a CT image with a high accuracy of data obtained, by surrounding a signal input pad into which a signal is inputted from an X-ray detector and a signal wiring pattern to an input terminal of an amplification circuit therefrom with a ground wiring pattern. CONSTITUTION:Conductive parts (a signal input bonding pad 34 and signal wiring pattern 35) to an input terminal of an amplification circuit with a high impedance from a signal input part from an X-ray detector are surrounded with a ground wiring pattern 37 with a low impedance. This portion shields the inflow of an ohmic current and diffusion current to the conductive parts. This eliminates mixture of these currents with signal currents, thereby providing a highly accurate data.
