This paper presents a low-noise active balun with broadband phase-correction. The proposed phase-correction structure is independent of operation frequency, and effectively suppresses phase deviation of active balun at millimeter-wave (MMW) band. Within the low noise current-reuse pre-amplifier, this active balun circuit can be employed as low-noise amplifier as well. This circuit is fabricated in...
A three stage transformer coupled amplifier for operation in the 57-64 GHz band is presented. The amplifier uses differential capacitive neutralization and low loss transformers to achieve a gain of 30 dB at 61 GHz. The amplifier has an output compression point of 7.5 dBm and a power added efficiency at 1dB compression of 9% at 57 GHz. The amplifier has been fabricated in digital CMOS and occupies...
This paper demonstrates that inserting a small resistance at the drain of a cascode LNA can be the simplest way of achieving higher bandwidth with only a slight degradation in noise figure. A 36.1 GHz single stage low noise amplifier is designed in 0.13 mum CMOS Process with a simple passive output matching circuit. The circuit is simulated using Cadence Spectre and simulation results show a forward...
A novel LNA topology with a transformer-based input integrated matching is proposed and its application to the 60-GHz millimeter-wave design in bulk CMOS 65 nm technology is reported. This topology exploits a novel technique to realize the input integrated matching (simultaneous input impedance and minimum noise matching to the source resistance) in cascode amplifier. This new technique does not require...
