Several applications with charge-coupled devices (CCDs) and Skipper-CCDs can be significantly improved with an enhancement in pixel readout speed. Skipper-CCDs can reach an extremely low readout noise using a floating gate (FG) that allows non-destructive readout (NDR) of the charge packet. In this seminar I will present the effort to integrate a dual-gate MOSFET, that has NDR capability like a FG but with higher sensitivity, into existing fully-depleted thick CCD designs. The second development is an imager fabricated in a CMOS process that has skipper-CCD readout stage on each pixel.
