Abstract
Amplifier circuits having at least one neuron MOS transistor in which a coupling gate is connected to an amplifier output and at least one further coupling gate is connected with a respective amplifier input are provided. The amplifier circuit exhibits a linear transmission behavior even in large-signal operation and can be constructed using relatively few components. Furthermore, the gain is easy to set.
Claims6
An amplifier comprising:
- a neuron MOS transistor having a first gate connected with an amplifier input and a second gate of the neuron MOS transistor is connected with an amplifier output wherein a first terminal of an apparatus for keeping a drain voltage constant of the neuron MOS transistor is connected with a constant current source and forms the amplifier output and further wherein a second terminal of the apparatus for keeping the drain voltage constant is connected with a first terminal of the neuron MOS transistor and still further wherein a second terminal of the neuron MOS transistor is connected with a fixed potential.
