In this letter, we present a rotation-aided arctangent phase discriminator (RaAPD) with one-bit analog-to-digital conversion. Different from the existing digital phase discriminator (DPD) and noise-balanced digital phase discriminator (NB-DPD), the proposed RaAPD can achieve higher accuracy and better noise robust features through utilizing an extra rotation channel in the arctangent phase discriminator...
This paper presents sub-THz interconnect for high energy-efficiency chip-to-chip communications, including a microstrip line based low-loss wideband sub-THz channel and a high energy-efficiency transceiver. The channel loss is as low as 0.06 dB/mm. The transmitter output power is 0.66 dBm with 8.8 mW of DC power consumption, and the receiver consumes 60.8 mW DC power. The interconnect achieves 9-Gb/s...
In this paper, a highly integrated direct conversion receiver MMIC for high speed E-band wireless communication is presented. The receiver consists of 3-stages LNA, doubler with buffer amplifier, and IQ-mixer. The LNA, doubler and IQ-mixer are also presented separately. The LNA covers 75 to 90 GHz with 15 dB gain and a simulated minimum 5 dB noise figure; doubler covers 75 to 90 GHz with 8 to 12 dBm...
