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 ...

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 ...

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 ...

It goes without saying that the smaller the device, the smaller the battery that it can support. Yet this doesn’t mean that consumers expect their wearable or hearable product to be short on battery ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...
