A 28GHz time-division multiple-input multiple-output (MIMO) receiver with eight radio frequency elements, each occupying just 0.1 mm, has been developed using 65nm CMOS technology. This innovative ...

However, work on this technique is distributed across the fields of photonics, radar, and signal processing. Pan et al.

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

In this issue of Hackaday Dictionary, we cover the multiplexer and demultiplexer (also called mux and demux). They are essentially opposites but they work on the same principle. There are three parts: ...

Fig 1. An SPI-based output driver (in this case, an L9822 octal relay driver from STMicroelectronics) can be used to provide a random mix of I/O pins at the chip’s output. The circuit in (a) senses a ...
