Scientists have achieved a milestone in creating a building block for the future of wireless devices. Researchers have announced the first integrated circuit fabricated from wafer-size graphene, and ...

Graphene circuit: This integrates a graphene transistor (inside the red box) with two other elements, called inductors, on a single chip. The black devices at the sides and top of the image are ...

CMOS mixers are integral components in modern radio frequency (RF) circuit design, enabling frequency conversion in wireless systems while prioritising low power consumption. Recent progress in ...

Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...

This FET audio mixer is an example of FET’s versatility. FETs are originally designed for high frequency applications but they can be used for audio frequencies and in fact they perform excellently in ...
