Current signals indicative of sensed physical quantities are collected from sensing transistors in an array of sensing transistors. The sensing transistors have respective control nodes and current channel paths therethrough between respective first nodes and a second node common to the sensing transistors. A bias voltage level is applied to the respective first nodes of the sensing transistors in the array and one sensing transistor in the array of sensing transistors is selected. The selected sensing transistor is decoupled from the bias voltage level, while the remaining sensing transistors in the array of sensing transistors maintain coupling to the bias voltage level. The respective first node of the selected sensing transistor in the array of sensing transistors is coupled to an output node, and an output current signal is collected from the output node.
