Abstract: Disclosed herein is an amplifier device that includes a plurality of transistor sets connected in series. The plurality of transistor sets include a first set of series-connected transistors of a first conductivity type and a second set of series-connected transistors of a second conductivity type. Each transistor of the first set of transistors is differently sized from each other of the first set of transistors. A first control terminal receives a first signal varying between a first upper voltage level and a first lower voltage level. A second control terminal receives a second signal varying between a second upper voltage level and a second lower voltage level. An output terminal coupled to a second transistor of the first set and a second transistor of the second set is configured to provide an output signal varying between the first upper voltage level and the second lower voltage level.

Abstract: Spiking neuron circuits and methods are provided in this disclosure. A spiking neuron may include a triggerable oscillator configured to generate an oscillator signal. The spiking neuron may further include a circuit configured to obtain an integration value based on received input spike signals. The spiking neuron may further include a leakage circuit configured to obtain a leakage value based on the oscillator signal. The spiking neuron may further include an oscillator activator configured to activate or deactivate the triggerable oscillator based on the leakage value and the integration value.

Abstract: Spiking neuron circuits and methods are provided in this disclosure. A spiking neuron may include a triggerable and frequency-controllable oscillator that is configured to generate an oscillator signal. The spiking neuron may further include a spike signal detector that is configured to generate spike detection signals in response to detection of input spike signals. The spike signal detector may generate the spike detection signals based on the oscillator signal. The spiking neuron may further include a neuron structure that is configured to provide an output spike signal based on the spike detection signals and the oscillator signal.
