Synapse circuit composed of a programmable amplifier and feedback logic (cf. Section 2.4 ) that implements the perceptron learning feedback ( 3 ) for a single weight. The upper amplifier when biased optimally leads to positive gain whereas the lower amplifier leads to negative gain due to the additional π phase shift.
