Ultrafast intrinsic optical-to-electrical conversion dynamics in a graphene photodetector Researchers demonstrated a gate-tunable graphene photodetector with a bandwidth of up to 220 GHz. This was achieved by suppressing the ‘RC’ time constant using a resistive zinc oxide top gate. Katsumasa Yosh...
A gate in digital electronics means a circuit whose output is a 1 only for some specified combination of inputs. This type of circuit is sometimes referred to as a combinational circuit. Note Do not confuse this with an analog gate circuit, which switches an analog waveform on or off depend...
Like an operational amplifier symbol, input and output connections are shown as single wires, the implied reference point for each voltage signal being “ground.” In digital gate circuits, ground is almost always the negative connection of a single voltage source (power supply). ...
Embedding security into ferroelectric FET array via in situ memory operation Existing solutions based Advanced Encryption Standard to address the security issues of nonvolatile memories incurs significant performance and power overhead. Here, the authors propose a lightweight XOR-gate based encryption/dec...

On the other hand, A 3-terminal device uses the gate and the channel as presynaptic and postsynaptic inputs, exhibits superior stability and effective channel conductance control. Chen et al. demonstrate how a graphene and ferroelectric insulator (polyvinylidene fluoride, i.e., PVDF) synapse can ...
By Gavin Wright Andrew Froehlich, West Gate Networks Definition 03 Apr 2023 ACK (acknowledgement) In some digital communication protocols, ACK -- short for 'acknowledgement' -- refers to a signal that a device sends to indicate that data has been received successfully. Continue Reading By Ra...
