A miniaturized Marchand balun combiner is proposed for a W-band power amplifier (PA). The proposed combiner reduces the electrical length of the transmission lines (transmission line) from about 80 <sup>&#x00B0;</sup> to 30 <sup>&#x00B0;</sup>, when compared with a conventional Marchand balun combiner. Implemented in a 1-V 65-nm CMOS process, the presented(More)
Co-design of 60-GHz wideband front-end integrated circuit (IC) with on-chip transmit/receive (T/R) switch in 65-nm CMOS is presented. Passive macro-modeling (pmm) is utilized to convert S-parameter files from passive component electromagnetic simulations to state-space models in circuit netlist format that could be used in a commercial SPICE simulator for(More)
A wide tuning range millimeter-wave voltage-controlled oscillator (VCO) based on a magnetically coupled &#x03C0;-type LC network in 65-nm CMOS is proposed. By configuring the switched negative-resistance unit, the VCO can oscillate at the even mode or the odd mode of the magnetically coupled &#x03C0;-type LC network, thus the tuning range is widened without(More)
A fully integrated 60-GHz 5-Gb/s quadrature phase-shift keying (QPSK) transceiver with the transmit/receive (T/R) switch in 65-nm CMOS is presented. By utilizing the co-design of the T/R switch with the power amplifier (PA)/low-noise amplifier, &#x03C0;-type wideband passive network technique, as well as the modified distributed-amplifier-based PA, the RF(More)
