Patent number: 10554178Abstract: In a preamplifier (amplifier) for the radiation detector, an interconnection layer connected to the bonding pad forms one electrode of a feedback capacitor. Since there is no wiring for connecting the bonding pad and capacitor, a parasitic capacitance caused by the wiring will not be generated. Moreover, the capacitor is arranged below the bonding pad with a conductive layer serving as the other electrode, so that the feedback capacitance of the capacitor is included in the parasitic capacitance between the interconnection layer and the substrate. Compared to the conventional case, an amount of capacitance corresponding to the parasitic capacitance caused by wiring and the feedback capacitance for the capacitor is reduced from the input capacitance. Thus, the input capacitance for the amplifying circuit is reduced.Type: GrantFiled: September 14, 2017Date of Patent: February 4, 2020Assignees: HORIBA, LTD., POLITECNICO DI MILANOInventors: Carlo Fiorini, Luca Bombelli

Patent number: 9411054Abstract: In a preamplifier (amplifier) for detecting radiation, an output of the preamplifier is set as an output of the first amplifying circuit, a capacitor is connected in parallel to the first amplifying circuit, and the second amplifying circuit with a positive gain of less than onefold is connected between the output terminal and the input terminal of the first amplifying circuit through a switch. When the switch is closed, the capacitor is discharged and reset. As the gain of the second amplifying circuit is less than onefold, the gain of the preamplifier is less than the loop gain of the first amplifying circuit alone during the reset operation, making it harder for oscillation to occur. Accordingly, the preamplifier can reduce the compensation capacitance compared to a conventional case and can shorten the reset time, while preventing oscillation.Type: GrantFiled: August 1, 2013Date of Patent: August 9, 2016Assignees: HORIBA, LTD., POLITECNICO DI MILANOInventors: Carlo Fiorini, Luca Bombelli
