Each readout circuit includes a buffered direct injection input circuit including a differential amplifier with active feedback provided through an injection transistor. The differential amplifier includes a pair of input transistors, a pair of cascode transistors and a current mirror load. Photocurrent from a photodetector can be injected onto
Multitude of pixel architectures: direct-injection (DI), capacitive transimpedance amplifier (CTIA), buffered direct injection (BDI), buffered gate modulation input (BGMI), along with custom circuits for ROIC pixels; Integrated on-ROIC reference generation and buffering; Integrated on-ROIC digital timing generation, control, register space 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.

Achieving BLIP performance in a direct injection readout
The DI Box - What is it? Why Do I Need One? | Sweetwater What Is a DI Box? Born out of necessity in studios such as Motown and United Sound Systems to accommodate the electric instruments emerging in the 1960s, direct boxes (also known as DIs, which stands for “Direct Inject”) began as a way to resolve a basic impedance mismatch between electrodynamic guitar pickups and sensitive studio electronics.. Although many modern DIs are far … 國立交通大學機構典藏：新型紅外線偵測器陣列之低 … By applying the proposed share-buffered direct-injection (SBDI) biasing technique and shared off focal-plane-array (off-FPA) integration capacitor structure, high-performance readout interface circuit for the IR FPA is realized with a pixel size of 50x50 mm2.An
A new share-buffered direct-injection readout structure
Achieving BLIP performance in a direct injection readout A study of effective injection efficiency as a function of RA (product of diode's dynamic impedance at the operating point and the area of diode) product in Hg 1-x Cd x Te hybrid focal plane array is reported and the role of buffered direct injection circuit in improving the effective injection efficiency has been investigated. This effective Strona główna - Wojskowa Akademia Techniczna 2020-5-1 · A buffered direct injection (BDI) circuit, shown in Fig. I(b), uses an inverting amplifier to reduce the in- put impedance, thus improving injection efficiency, bias stability, and frequency response. It can maintain relatively constant detector bias at medium and … A high-precision and high-linearity readout integrated 2019-5-1 · Moreover, buffered direct injection method is adopted in the bias circuit in order to ensure the bias point stability and reduce the non-uniformity.
