Abstract

Millimeter-wave on-off keying (OOK) modulator for wireless inter-chip communications is proposed. The proposed modulator not only has a wide bandwidth which allows the high speed modulation but also operates with a low power consumption enhancing the power efficiency and assures the inter-chip communication. With wide bandwidth and the OOK modulation scheme, it can process data having 12 Gbps while consuming a little DC power showing the energy efficiency of 0.75 pJ/bit. The on/off ratio of the circuit is higher than 25 dB assuring little degradation on the SNR. The chip size using 65nm GP RF CMOS is 0.254 mm2 which is very compact compared to other state-of-the-art works.
