In this letter, a second harmonic suppressed millimeter-wave (mm-wave) gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifier (PA) using the self-resonate characteristic of the capacitor is proposed. Based on a simple modified band-pass output matching network, a novel second harmonic suppression method by utilizing the self-resonate characteristic of the on-chip capacitor is proposed, which can realize the harmonic suppression without any additional tuning structures. For verification, a 24-to-28-GHz GaN MMIC PA was designed using a 150-nm GaN on silicon carbide high electron mobility transistor process. The fabricated PA achieved a saturated power range of 32.5-34 dBm, with a corresponding power-added efficiency (PAE) of 37.5%-44.5%. The amplifier achieved good linearity when excited by a 400-MHz orthogonal frequency division multiplexing signal after applying digital predistortion.
本文提出了一种利用电容自谐振特性的二谐波抑制毫米波(mm-wave)氮化镓(GaN)单片微波集成电路(MMIC)功率放大器。基于一种简单的改进带通输出匹配网络，提出了一种利用片上电容自谐振特性的二次谐波抑制方法，该方法无需额外的调谐结构即可实现谐波抑制。为了验证这一点，我们采用150纳米碳化硅高电子迁移率晶体管工艺设计了24 ~ 28 ghz GaN MMIC放大器。所制备的PA达到了32.5-34 dBm的饱和功率范围，相应的功率附加效率(PAE)为37.5%-44.5%。采用数字预失真后，在400 mhz正交频分复用信号的激励下，放大器获得了良好的线性度。

This paper presents a 12-bit 2.32 GS/s time-interleaved pipelined/successive-approximation register (SAR) hybrid analog-to-digital converter (ADC) implemented in 28 nm CMOS. To achieve high-linearity at several GS/s, a pseudo-differential push-pull input buffer with floating-body technique is proposed. A pipelined/SAR hybrid architecture with dual-channel sampling multiplying digital-to-analog converter (MDAC) and one shared flash sub-ADC is used exploiting a simple calibration. The ADC achieves a signal-to-noise-and-distortion-ratio (SNDR) of 55.68dB and a spurious-free-dynamic-range (SFDR) of 72.18dB at 1125MHz input and consumes 175 mW.

The output voltage and reference current are to be considered in the design of voltage outer loop for boost PFC converter. However, the dynamic response of output voltage and reference current accuracy affects each other, which complicates the compensator design. In this letter, a voltage outer-loop compensator method is proposed to design the compensator parameters by non-dominated sorting and hierarchical clustering algorithms with the output voltage dynamic performance and reference current accuracy as the objectives, respectively. It ensures the reference current accuracy while improving the performance of output voltage dynamic response. The experimental results verify the effectiveness of the method.

This paper proposes a multicell-to-multicell (MC2MC) equalizer based on the half-bridge bipolar-resonant LC converter (HBBRLCC), which collects energy from the consecutive more-charged cells (high-voltage group) through the positive and negative polarity selection switch matrix and the half-bridge switch matrix, and then releases the energy to the consecutive less-charged cells (low-voltage group). The paper includes configuration of the proposed equalizer, the mathematical model and simulation comparison with conventional equalizers, highlighting the superior high-speed balancing performance and excellent balancing efficiency of the proposed equalizer. An experimental prototype is built with four cells to verify the performance, and the balancing efficiencies in different balancing modes range from 81.45% to 87.62% with an average balancing power of 1.454 W to 5.011 W.

To address the issue of poor dynamic regulation caused by uncertainties and disturbances in the external conditions of the High step-up quasi-Z-source dc-dc boost converter (HSQZSC) control system, an integral sliding mode (ISM) controller is designed to ensure system robustness and fast response. Firstly, the operating principle of HSQZSC is analyzed to establish a mathematical model. Secondly, a sliding surface is designed using the output voltage error, inductor current error, and their integrals as state variables. Then, the conditions for stable operation of ISM are derived, and the parameter design is analyzed. Finally, by comparing with conventional control strategy using simulation and experimental platform, the results demonstrate the feasibility and effectiveness of the designed ISM control strategy.
