This phenomenon is consist with the electric field distribution simulation result with the help of the software ANSYS. Eight photographs in double trigger mode prove that the breakdown time of the gas triggered switch is above 10.5 microseconds.The elementary results show that high speed camera is a very efficient apparatus to study the discharge characteristics.This optical measuring technique is helpful to profoundly study the breakdown of high voltage switch. More studies and experiments would be continued in future.展开更多

The area of the proposed 1.5 transistor (1.5T) OTP cell is 2.13 μm2, which is a 49.3% size reduction compared to the previously reported cells. The 1.5T cell is fabricated and measured and shows a large programming window without any disturbance. A novel high voltage switch (HVSW) circuit is also proposed to make sure the OTP macro, implemented in a standard CMOS process, works reliably with the high program voltage. The OTP macro is embedded in negative radio frequency identification (RFID) tags. The full chip size, including the analog front-end, digital controller and the 4-kbit OTP macro, is 600 × 600 μm2. The 4-kbit OTP macro only consumes 200 × 260 μm^2. The measurement shows a 100% program yield by adjusting the program time and has obvious advantages in the core area and power consumption compared to the reported 3T and 2T OTP cores.展开更多
