A Survey of Power Supply Techniques for Silicon Photo-Multiplier Biasing
نویسندگان
چکیده
In the past few years Silicon Photo-multiplier (SiPM) has emerged as a new detector in various applications due to its promising characteristics for low light detection. However SiPM has certain limitations out of which temperature dependence of gain is an important parameter which limits the application fields to temperature controlled or indoor environment. Change in temperature changes the breakdown voltage and hence the gain; therefore the biasing voltage needs to be trimmed according to temperature for maintaining the constant gain. This paper explores different power supply techniques that have been used for SiPM. Many commercial power supplies are compared and different approaches which are tried by various research groups for maintaining stable gain are discussed. Keywords— Silicon Photomultiplier, SiPM, Power Supply, Temperature Compensation, Bias Correction of SiPM, Gain stabilization, Automatic Gain Correction.

متن کاملThe Effect of DTMOS Transistors on the Performance of a Memristor-based Ternary CAM Cell in Low Power Applications
This paper proposes the use of DTMOS transistors in a memristor-based ternary CAM (MTCAM) instead of MOSFET transistors. It also evaluates the effect of forward body biasing methods in DTMOS transistors on the performance of a MTCAM cell in write mode. These biasing methods are gate-to-body tying (called DT1), drain-to-body tying (called DT2), and gate-to-body tying with a voltage supply of 0.1...
