Fig. 1: Frequency converter in wireless internet-of-things (WIoT).
a Classical wireless IoT applications at smart home or smart factory interacting with remote central cloud at low frequency bands. b Wireless data transmission link in WIoT hardware, including a variety of sensors, pre-processor, frequency converter and radio frequency circuitries. c Classical CMOS-based frequency converter using complex digital and analog circuits with separate frequency synthesizer and mixer modules, incurring excessive latency and energy consumption. d Our VO2-based memristive oscillators build a frequency converter with in-situ frequency synthesize and mix for reduced latency and energy.
