新型低功耗QSBDI红外读出电路设计 - PKU 2006-9-22 · Abstract: A novel low power Quad-Share Buffered Direct-Injection (QSBDI) readout circuit for large format staring ROIC is proposed. In this circuit, four pixels share one common buffer amplifier. With switches' cooperation, the circuit can achieve ITR (integrate then readout) and IWR (integrate while readout) function. Electronically scanned buffered direct injection circuit 1995-1-17 · The present invention comprises an electronically scanned buffered direct injection (ESBDI) readout circuit and architecture for coupling a mosaic of detectors, thereby forming an infrared focal plane array (IR FPA). A typical IR FPA is a hybrid device that includes a mosaic of HgCdTe detectors on a transparent substrate. A new share-buffered direct-injection readout structure

The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high current and low output voltage drop features make this device suitable for controlling direct injection actuators and for use in many automotive DC−DC converter and motor control applications. Features Mathematical Modeling of Multi-Element Infrared Focal 2018-9-25 · the input impedance of readouts, the so-called buffered direct injection, implemented through introduction of an inverting amplifier in between the input direct injection and input FET gate. J. Longo et al. (Longo, 1978) proposed a design of dire ct injection readout circuit capable of
A new current readout circuit for infrared (IR) detectors, called the Share-Buffered Direct-injection (SBDI) circuit, is proposed and analyzed. It is found that the proposed SBDI readout structure can achieve the high readout performance as the conventional Buffered Direct-Injection structure (BDI), but only with half chip area and power
