How Do You Calculate Power Efficiency in DTC Networks?

AI Thread Summary
To calculate power efficiency in DTC networks, it's essential to understand that supply power and power in are equivalent, particularly for DC systems, where a power factor is not necessary. The spec sheet provides supply voltage and current, which can be used to determine supply power. It is important to focus on specifications related to output power to assess performance gain and efficiency. In signal processing chips, supply power generally exceeds signal power significantly. Understanding these terms will aid in accurately modeling the phone's performance improvements.

Hi,
I am trying to model a phones increased performance due to the integration of a DTC network. I have the spec sheet on the part but for the live of me cannot interpret it to generate the information I need. I need to find the Power in and out of the component to determine gain and efficiency. They give me supply Voltage and Current so I can find supply Power...(right?), but the rest is in terms I can't understand. Which of the specs should I focus on, and what might they be termed?
Also for Power IN is that the same as Supply Power or do I need a power factor? Any help would be sooo appreciated.
Thank you,
Christa

Yes, the power in and supply power are the same thing. The supply is DC correct? If so, then you don't need a power factor.

In a signal processing chip, supply power is typically much larger than signal power.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
