Abstract
The invention relates to a method of detecting alpha particles in SOI technology and a circuit thereof. The structure is a silicon-on-insulator radiation detector which includes: a charge collection node; a precharge transistor that has a source from the charge collection node, a drain at Vdd, and a gate controlled by a precharge signal; an access transistor that has a source from the charge collection node, a drain connecting to a readout node, and a gate controlled by a read-out signal; and a detector pulldown transistor having a drain from the charge collection node, a source to ground, and a grounded gate.
