RFIC chip set employing silicon CMOS technology for applications to millimeter-wave system

This paper presents a low-power front-ended 24 GHz receiver resistive mixer and buffer amp, which were fabricated using 0.13 μm RF CMOS technology for application to automotive radar. For resistive receiver mixer, single-ended resistive mixer was designed for high linearity characteristic and low power consumption. According to measured results, the proposed resistive mixer showed an improved linearity and low power consumption characteristic. At 24 GHz, the resistive receiver mixer showed a conversion loss of -9 dB and an input 1-dB gain compression point of -1 dBm at a low bias voltage of 0.3 V. The buffer amplifier showed a gain of 4.5 dB at 24 GHz.
