In this paper, a wide-band noise-canceling (NC) current conveyor (CC)-based CMOS low-noise amplifier (LNA) is presented. The circuit employs a CC-based approach to obtain wide-band input matching without the need for bulky inductances, allowing broadband performance with a very small area used. The NC technique is applied by subtracting the input t...

Single event transients (SETs) in analog integrated circuits result from the interaction of a heavy ion or high-energy proton with a sensitive p-n junction. SETs induce electron-hole pairs that can lead to current spikes, which propagate through the integrated circuit and can result in substantial transient peaks at the output voltage. This paper p...
