Common-base amplifiers produce a high voltage gain and a maximum current gain of one. Because common-base amplifiers have a low input resistance, circuit designs will use common-base configurations for communication systems that require source impedance matching. DC Analysis of BJT Amplifier Circuits ...
You can use the same formula to calculate your week-over-week growth or year-over-year growth. Now, say you want to calculate your MoM growth rate over six months instead of your growth rate for one month. That’s when you want to calculate your compound monthly growth rate. Compound mo...
Emitter degeneration refers to the addition of a small resistor (R4) between the emitter and the common signal source. In this circuit the base terminal of the transistor is the input, the collector is the output, and the emitter is common to both. It is a voltage amplifier with an ...
The input resistance is usually calculated with a test source connected at the amplifier input. Its value can be easily derived if we know the test source and the current it sources into the circuit under test. For this task, let’s replace the transistor with its small-signal equivalent as...

Some studies have revealed that daily feeding may not be necessary for maximum weight gain [2]. At the same time, a positive correlation has been found between weight gain and feeding frequency [3]. It has been reported that juvenile Korean rockfish showed higher growth when fed every other ...
tendentially docile temperament and few ethical restrictions associated with its scientific use [7]. In fact, recently, this animal model has begun to gain some attention in this field of research [8]. In the past, our group developed a new protocol for the induction of lesions in the comm...
Epigenetic modifications are considered of utmost significance for tumor ontogenesis and progression. Especially, it has been found that miRNA expression, as well as DNA methylation plays a significant role in central nervous system tumors during childho
The second source of information was Eurostat data, which provided information about pure biodiesel production in the European Union (EU) countries from 2004 to 2019. The biggest producers of pure biodiesel in the European Union are Germany, France, Spain, and Italy. Poland is also an important...
Serum biochemical parameters are functional tools to understand health and the physiological status of fish. For example, the primary source of energy for fish is glucose and the glucose is a biomarker of physiological stress. In addition to this the activity levels of serum aspartate aminotransferase...
