Abstract: A pixel driving circuit includes a first transistor, a second transistor, and a first capacitor. The first transistor is configured to receive a data signal and drive a light emitting element based on the data signal. The first transistor includes a first gate terminal, a first source terminal, and a first drain terminal. The second transistor includes a second gate terminal receiving a first bias signal from a first bias source, a second source terminal coupled to the first transistor, and a second drain terminal coupled to the light emitting element. The first capacitor is disposed between the first gate terminal and the second gate terminal. The first transistor and the second transistor are different types of transistors.

Abstract: Embodiments of pixel circuits for light emitting elements are disclosed herein. In one example, a pixel circuit includes a pixel driver and a bridge transistor. The pixel driver is configured to receive a data signal and drive a light emitting element based on the data signal. The bridge transistor includes a gate terminal receiving a first bias signal, a source terminal coupled to the pixel driver, a drain terminal coupled to a terminal of the light emitting element, and a body terminal coupled to the source terminal or receiving the data signal. The first bias signal controls a voltage at the source terminal.

Abstract: A current measurement circuit for measuring a current consumption of a circuit system includes a plurality of current measurement units and a current-to-voltage (I-V) converter. Each of the current measurement units includes an impedance unit and a voltage-to-current (V-I) converter. The impedance unit includes a first terminal and a second terminal. The V-I converter, coupled to the first terminal and the second terminal of the impedance unit, includes an output terminal and an operational transconductance amplifier (OTA). The plurality of output terminals of the plurality of V-I converters of the plurality of current measurement units are coupled to a first node. The I-V converter is coupled to the first node.
