本红外探测器装有一个能将入射红外辅射转换成电信号的辐射热计(1)。N型MOS场效应管(2)的漏极与辐射热计的第二端子相连,而其源极则与电源相连。一个转移栅极(AND4)连接N型MOS场效应管的源极。
The infrared detector incorporates a bolometer (1) that converts incident infrared (IR) radiation into electrical signals. The drain of the N-type MOS field-effect transistor (2) is connected to the second terminal of the bolometer, and its source is connected to the power supply. A transfer gate (AND4) connects the source of the N-type MOS FET.
