Abstract
A resistive processing unit (RPU) includes a circuit including at least two current mirrors connected in series, and a capacitor connected with the at least two current mirrors, the capacitor providing a weight based on a charge level of the capacitor. The capacitor is charged or discharged by one of the at least two current mirrors.
