Abstract

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 between the transmitter and receiver coils, the reliability of the chip-to-chip communication is improved compared to a pulse-type transceiver. To verify the feasibility of the proposed transceiver, we design a transceiver using a 180 nm CMOS 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.
