    Abstract: A readout circuit for an uncooled infrared focal plane array includes: a first biasing circuit for generating a detection output signal; a second biasing circuit for generating a first reference output signal; a first integration circuit; and an analog-to-digital circuit including: a ramp signal generating circuit for generating a ramp signal according to a second reference microbolometer of a third biasing circuit. In the readout circuit, subtracting and amplifying the detection output signal and the first reference output signal are provided by the integrator at an analog domain, while ratio counting is provided by an analog-to-digital converter during analog-to-digital conversion. Furthermore, a column level integrated readout channel utilizes only one reference microbolometer, and the chip level ramp signal generator also utilizes only one reference microbolometer. Therefore, a chip area is further saved, and noise sources are decreased.

    Abstract: A pipelined processor including a combinational logic of several stages, a voltage regulator, a counter, a comparator, and a plurality of stage registers. Each stage register is disposed between two adjacent stages of the combinational logic. The stage register includes a flip-flop, a latch, an XOR gate, and a MUX module. When the high level of a register clock is coming, the flip-flop latches first data at the rising edge, and the latch receives second data during the high level. The data latched by the flip-flop and the latch respectively are compared by the XOR gate. If they are same, the output Error of the XOR gate is low level, and the output of the flip-flop is delivered to the next stage. Otherwise, the output Error of the XOR gate is high level, and the output of the latch is delivered to the next stage.

    Abstract translation: 一种流水线处理器,包括几级的组合逻辑,电压调节器,计数器,比较器和多个级寄存器。 每个级寄存器被布置在组合逻辑的两个相邻级之间。 级寄存器包括触发器,锁存器,异或门和MUX模块。 当寄存器时钟的高电平到来时,触发器在上升沿锁存第一数据,并且锁存器在高电平期间接收第二数据。 由触发器和锁存器锁存的数据分别由XOR门进行比较。 如果它们相同,则XOR门的输出误差为低电平,触发器的输出被传送到下一级。 否则,异或门的输出误差为高电平,并将锁存器的输出传送到下一级。

    Abstract: A multi-level gate driver applied to the SiC metal-oxide-semiconductor field-effect transistor (MOSFET) includes three parts: the SiC MOSFET information detection circuit, the signal level shifting circuit, and the segmented driving circuit. The SiC MOSFET information detection circuit includes the SiC MOSFET drain-source voltage detection circuit and the SiC MOSFET drain-source current detection circuit. The segmented driving circuit includes a turn-on segmented driving circuit and a turn-off segmented driving circuit. The SiC MOSFET drain-source voltage detection circuit and the SiC MOSFET drain-source current detection circuit process a drain-source voltage and a drain-source current during the SiC MOSFET's switching as enable signals for segmented driving; the signal level shifting circuit transfers enable signals required by the segmented driving circuit to the suitable power supply rail; and the SiC MOSFET turn-on segmented driving circuit and the turn-off segmented driving circuit select suitable driving currents.

    Abstract: Provided are a scattering aperture imaging method and a device, a system and a storage medium. The method mainly includes four steps of scattering point position estimation, azimuth resampling, range compensation and synthetic aperture radar imaging. A phased array radar with a fixed position is used for NLOS imaging, and the radar can control a beam to scan in space, which is equivalent to a scattering aperture moving along a relay surface. Therefore, the method can realize converting NLOS imaging into LOS synthetic aperture radar imaging, which can be suitable for the situation that a relay surface is rough and the relay surface with more complicated surface condition, thus widening the application range of radar NLOS imaging.
