The effect of an in-mold static mixer on orientation fiber-reinforced polypropylene (PP) was explored within the injection molding process. Several mold geometries and helical designs were assessed via simulation to identify mixing ability potential fiber orientation. It found that mixers runner segment could successfully mix polymer randomize fibers but alignment reduction quickly recovered. I...

This paper proposes a low-power all-digital phase-locked loop (ADPLL) with calibration-free ring oscillator (RO)-based injection-locking time to digital converter (TDC) for BLE applications. The RO is reused as the delay cell of TDC, and quantization step TDC always tracked period; hence no calibration needed in this architecture. We adopt tuning lower bandwidth so decrease power consumption in...

The two-frequency problem of synchronization of the pulse train of a passively mode locked soliton laser to an externally injected pulse train is solved in the weak injection regime. The source and target frequency combs are distinguished by the spacing and offset frequency mismatches. Locking diagrams map the domain in the mismatch parameter space where stable locking of the combs is possible....

A prototype dual-mode voltage-controlled oscillator supporting two simultaneous oscillation modes is fabricated and demonstrated in a 0.18 mm CMOS process. The oscillator has two resonant ports while sharing one bias. Injection locking is applied to lock the low frequency, 4.8 GHz, to half of the high frequency, 9.6 GHz. The oscillator core consumes 7 mA from a 1.8 V supply. Measurement shows a...

We have developed an amplifier which removes its "offset" as a natural part of its operation by modifying the charge on a floating gate. The charge on the floating gate is adapted by a combinat,ion of electron tunneling and hot-electron injection, resulting in a nonlinear high-pass filter with a cutoff frequency less than 1 Hz. We show experimental data from this autozeroing amplifier for vario...

A sensorless online temperature estimator is presented in this paper, which estimates the using a novel signal injection strategy. This allows to eliminate sensors machine, as well their faults, increasing system reliability. double dead-time DC injected adding controlled offset control drive through inverter. The proposed strategy eliminates effect of signal, an important drawback strategies f...

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...

ARC-520 Injection, an RNA interference drug for the treatment of hepatitis B that targets cccDNA-derived viral mRNA transcripts with high specificity, effectively reduces the production of viral proteins and HBV DNA. In this phase 1 randomized, double-blind, placebo-controlled study, 54 healthy volunteers (half male, half female) received a single, intravenous dose of 0.01-4.0 mg/kg ARC-520 Inj...
