We demonstrate so-called repetitive non-destructive readout (RNDR) for the first time on a single electron sensitive readout (SiSeRO) device. SiSeRO is a novel on-chip charge detector output stage for charge-coupled device image sensors, developed at MIT Lincoln Laboratory. This technology uses a p-MOSFET transistor with a depleted internal gate beneath the transistor channel. The transistor source-drain current is modulated by the transfer of charge into the internal gate. RNDR was realized by transferring the signal charge non-destructively between the internal gate and the summing well (SW), which is the last serial register. The advantage of the non-destructive charge transfer is that the signal charge for each pixel can be measured at the end of each transfer cycle, and by averaging for a large number of measurements ( |
