What are good papers that explain the delta method of minimizing offset thermal EMFs?
5 answers
The delta method for minimizing offset thermal EMFs is well explained in the paper by Rodenbeck et al., where they introduce a technique called "delta modulation" (DM) to improve the sensitivity of RF subsamplers in radar and coherent receiver applications. This method involves feeding the time-average output of a monobit analog-to-digital converter (ADC) back to the ADC input with opposite polarity to correct for aggregate DC offsets, enhancing ADC sensitivity. The paper demonstrates the effectiveness of analog and digital DM circuits in correcting output quantization imbalance, even under varying temperature conditions, and improving baseband spectrum quality for realistic radar applications. The DM technique does not impact ADC linearity, as confirmed through two-tone testing.
How transparent oxides can be used as gate dielectric?
5 answers
Transparent oxides can be utilized as gate dielectrics in various applications. For instance, in the study by Alshammari et al., a novel process was developed to fabricate thin film transistors (TFTs) using a binary oxide, Hf x Zn1- x O2- δ (HZO), for all transistor layers, including the gate and dielectric layers. This approach allowed for tuning the electronic properties of the oxide from conducting to insulating by adjusting the chemical precursors' flow ratio. Additionally, the work by ViolBarbosa et al. demonstrated that ionic liquid gating can induce a metallic phase in insulating films of WO3, altering the material's conductivity while maintaining transparency in the visible range. These studies highlight the versatility of transparent oxides in serving as gate dielectrics with tunable electronic properties for various electronic devices.
What is the difference between constant voltage and constant current in gel electrophoresis?
5 answers
In the context of gel electrophoresis, the difference between constant voltage and constant current lies in their control mechanisms and adaptability. Constant current control in microchip electrophoresis directly indicates the velocity of the electroosmotic flow (EOF), making it more convenient than constant voltage control. Constant voltage electromigration testing offers advantages over constant current testing for materials with varying geometries, while the benefits are minimal for properly produced materials. A constant current circuit with high breakdown-voltage transistors is designed for high voltage circuits with low manufacturing costs. Additionally, a constant current constant voltage circuit stabilizes voltage and controls levels effectively, featuring strong anti-interference capabilities. These findings highlight the nuanced differences and applications of constant voltage and constant current in gel electrophoresis.
