An electronic device comprising at least one die stack having at least a first die (D) comprising a first array of light emitting units (OLED) for emitting light, a second layer (D) comprising a second array of via holes (VH) and a third die (D) comprising a third array of light detecting units (PD) for detecting light from the first array of light emitting units (OELD) is provided. The second layer (D) is arranged between the first die (D) and the third die (D). The first, second and third array are aligned such that light emitted from the first array of light emitting units (OLED) passed through the second array of via holes (VH) and is detected by the third array of light detecting units (PD). The first array of light emitting units and/or the third array of light detecting units are manufactured based on standard semiconductor manufacturing processes.

Electronic device and method of manufacturing an electronic device

A variety of circuits, methods and devices are implemented for radiofrequency amplifiers. According to one such implementation, a radiofrequency amplifier circuit is implemented in a SMD package. The circuit amplifies a radiofrequency signal having a base-band portion and a plurality of carrier signals frequency-spaced larger than the base-band bandwidth. The circuit includes a radiofrequency transistor connected to a circuit output having a parasitic output capacitance. The source-drain terminal is electrically connected to the circuit output. An internal shunt inductor provides compensation for the parasitic output capacitance. A high-density capacitor is connected between the internal shunt inductor and a circuit ground. The high-density capacitor has a terminal with a surface area can be at least ten times that of a corresponding planar surface.
