An rf transceiver for wireless chip-to-chip communication using a cross-coupled oscillator

초록

In this study, we propose a transceiver architecture for wireless chip-to-chip communication using on/off keying (OOK) modulation. The proposed transceiver is composed of an oscillator, coils, an envelope detector, and a Schmitt trigger. Given that the oscillator itself acts as an OOK modulator, the transmitter is simplified. Additionally, because the oscillating signal is coupled with the transmitter and receiver coils, the chip-to-chip communication reliability is improved compared to a pulse-type transceiver. To verify the feasibility of the proposed transceiver, we design a transceiver using a 180-nm complementary metal-oxide-semiconductor process. For a design with a 1.5-GHz oscillation frequency and 1-MHz digital input signal, we verify that the proposed transceiver successfully recovers the original digital signal. © 2019 Electromagnetics Academy.
