To overcome hardware limitations, introduced by analog impairments, digital correction and alignment algorithms are employed for compensation.
On the other hand, the recent and ongoing realization of gigabit-per-second capable cellular modems is driving hardware and power requirements to extremes. As a result, the desire for the radio nodes to harvest their operational energy from the environment emerges. This demand is caused by massive deployment scenarios of billions of devices, which makes wires and batteries unpractical. They should be constructed as energy-autonomous, wireless, low-cost sensor nodes.
On the brink of introducing the fifth generation (5G) of cellular networks, the art of radio-frequency (RF) integrated circuit design has never seen such a wide spread of diverging requirements: On the one hand, ubiquitous sensor networks are mandating power budgets in the order of micro-watt.
