Abstract
This article presents a fully integrated, wireless,
RF-powered data transceiver for high-performance implants,
such as neural interfaces. The design occupies a total volume
of 1.6 mm
3 with no need for an off-chip component. The
integrated circuit (IC) receives power and downlink data with
amplitude-shift-keying (ASK) modulation by an on-chip coil
through an RF wireless link. For uplink data transmission,
we designed a transmitter (TX) based on a power oscillator
stage directly connected to an o
