Millimeter-Wave Integrated Circuits in 65-nm CMOS |
| |
Abstract: | We present the design and measurement results of millimeter-wave integrated circuits implemented in 65-nm baseline CMOS. Both active and passive test structures were measured. In addition, we present the design of an on-chip spiral balun and the transition from CPW to the balun and report transistor noise parameter measurement results at V-band. Finally, the design and measurement results of two amplifiers and a balanced resistive mixer are presented. The 40-GHz amplifier exhibits 14.3 dB of gain and the 1-dB output compression point is at $+$6-dBm power level using a 1.2 V supply with a compact chip area of 0.286 ${hbox{mm}}^{2}$. The 60-GHz amplifier achieves a measured noise figure of 5.6 dB at 60 GHz. The AM/AM and AM/PM results show a saturated output power of $+$7 dBm using a 1.2 V supply. In downconversion, the balanced resistive mixer achieves 12.5 dB of conversion loss and $+$5 dBm of 1-dB input compression point. In upconversion, the measured conversion loss was 13.5 dB with $-$19 dBm of 1-dB output compression point. |
