Abstract
A circuit includes an electroluminescent (EL) device, a transistor, a first capacitor and a second capacitor. The transistor includes a gate coupled to a first node and a first terminal coupled to a second node. The first capacitor is coupled between a supply voltage and the first node. The second capacitor is coupled between the first node and the second node. The first capacitor and the second capacitor are configured to establish a compensation voltage associated with a threshold voltage of the transistor at the gate of the transistor in response to a first control signal, and establish the compensation voltage at the first terminal of the transistor in response to a second control signal. The transistor is configured to pass a current through the EL device. Moreover, the current has a magnitude independent of the threshold voltage of the transistor.
