This work presents an ultra-wideband (UWB) low noise amplifier (LNA) with active shunt-feedback technique for wideband and flat gain by using standard 0.18μm CMOS processes. Different from past resistive shunt-feedback technique, the capacitor supersedes by a transistor in active shunt-feedback technique. The active shuntfeedback provides input matching(More)
A novel type of amorphous silicon (a-Si) thin-film transistor (TFT) in which a depletion gate is added to the top of the second nitride layer of a conventional a-Si TFT has been fabricated. In this transistor, switching is done by the depletion gate instead of the accumulation gate as in conventional a-Si TFTs. The pinch-off voltage and ON-OFF current ratio(More)
