Nonnegative tensor decomposition has become increasingly important for multiway data analysis in recent years. The alternating proximal gradient(APG) is a popular optimization method for nonnegative tensor decomposition in the block coordinate descent framework. In this study, we propose an inexact version of the APG algorithm for nonnegative CANDECOMP/PARAFAC decomposition, wherein each factor matrix is updated by only finite inner iterations. We also propose a parameter warm-start method that can avoid the frequent parameter resetting of conventional APG methods and improve convergence *** experimental tests, we find that when the number of inner iterations is limited to around 10 to 20, the convergence speed is accelerated significantly without losing its low relative error. We evaluate our method on both synthetic and real-world *** results demonstrate that the proposed inexact APG algorithm exhibits outstanding performance on both convergence speed and computational precision compared with existing popular algorithms.

Universal Asynchronous Receiver/Transmitter, commonly known as UART, is a configurable single-bit serial transmit and receive communication interface, which supports various baud rates, optional 5–8 bits of data length, parity check and optional 1–2 bits of stop bit. With the rapid development of MCU in the field of automotive electronics, the MCU that meets the requirements of vehicle regulations should have high reliability and efficient fault detection, and the application of the self-test function in UART can effectively improve the reliability and detection efficiency. The design is based on the self-test function and UART protocol design, using finite machine control timing, allowing the self-test controller to complete the self-test without manual configuration after receiving the self-test signal. The RTL of the UART and the self-test function are developed in Verilog, and the simulation verification is done in NCVerilog.

A two-stage common source wideband power amplifier with negative feedback network is presented in this paper. The design uses a negative feedback structure to improve the bandwidth and stability, and the matching network is also designed elaborately to meet the broadband requirements. The theoretical analysis of broadband design based on the parasitic effect of transistors is introduced and carried out in details in the paper. The bandwidth expanding technique with negative feedback structure are also analyzed. The dedicated theory analysis method is different from the impedance matrix theoretical wideband analysis in other designs. The proposed power amplifier designed based on a 0.25µm GaN process, has a saturated output power greater than 26dBm in the 8GHz-18GHz wide operating band, a maximum dynamic current of less than 149mA, and has a compact size of 1.7mm×1.1mm.
