【発明の名称】フオ-カルプレ-ン検出器アレイにおける前置増幅器
Document Type and Number:
Japanese Patent JPS61500636
Kind Code:
A
Abstract:
A pre-amplifier located "at the focal plane" of a detector array is disclosed which uses MOSFET transistors operated in the "weak inversion" region to provide operational amplifier performance. The dimensions of certain of the transistors are designed to minimize noise amplification. Feedback resistance for the operational amplifier is provided by switched capacitance using MOSFET transistors as switches, thereby permitting adjustment of the amplifier gain. Implanted and non-implanted MOSFET transistors are used in the differential amplifier in such a way as to avoid the need for a biasing network.
