Author(s): Xinyi Wu, Chenxu Zhao, Hui Chen, Xun Bao, Yaolong Hu, Aoyang Zhang, Leibo Liu

Abstract:

This letter presents a compact, multiband reflection-type phase shifter (RTPS) implemented in 65-nm CMOS that overcomes the narrowband limitations of conventional passive loads. The proposed design utilizes an inductive-load modulation. By injecting a secondary signal to actively manipulate the magnetic flux, the equivalent inductance is boosted to enable operation across …

Abstract:

The proposed capacitor-free hybrid-process low-dropout regulator (LDO) achieves 900-mA maximum current capacity and 99.99% peak current efficiency with 90 $\mu $ A quiescent current. By combining GaN and silicon processes, the proposed Ultrahigh gain amplifier (UHGA) enables a high loop gain to achieve 0.297-mV/A load regulation and 0.024-mV/V line regulation. Furthermore, …

A Millimeter-Wave Standing-Wave Oscillator With Frequency-Specific Wave-Velocity Control Demonstrating Class-F Effects

A Millimeter-Wave Standing-Wave Oscillator With Frequency-Specific Wave-Velocity Control Demonstrating Class-F Effects 150 150
Author(s): Wei-Yu Lin, Jun-Chau Chien

Abstract:

Implementing dual-resonance class-F oscillators with transformer feedback beyond 60 GHz poses significant challenges due to the limited third-harmonic tank impedance when using small coils with low coupling factors. To address these limitations and leverage the phase noise advantages of class-F operation, this letter introduces a standing-wave oscillator (SWO) topology featuring an …
