For detector with long charge collection times, such as NaI(Tl) detectors, proportional counters, coax Ge - detectors, the output rise time of the preamplifier is controlled by the detector charge collection time. The output rise time can range up to 700ns, for large Ge - detectors, and ~500ns for NaI(Tl) detectors.

My homebrew RF power meter has 2 inputs. 1) using a 1N4148 peak detector and 2) using a 1N34A diode as the peak detector. This second port will read RF power from approximately 20dBm - 0dBm. Therefore, the values of Parameters are as below: L = 80 uH, internal resistance Rint ~ 0.5 Ω C = 1.8 uF The resonance frequency: 1 1 fr ~ 13Khz (4.1.5) 2 LC 2 80.10 6.1.8.10 6 Transfer function: Y ( s) Rs Cs (4.1.6) X ( s) LCs ( Rint Rs )Cs 1 2 Base on the transfer function, the value of peak voltage and peak current according to variable ... NOTE: LTSPICE screenshot used for simulation. There are two secondaries, 6 turns each. By using two voltage sampling networks, the problem of voltage divider loading was solved and with the help of the compensation resistor I got a very good behaviour over the 1.8-50 MHz range.

The space vector modulation technique differs from the hysteresis modulation in that there are not separate comparators used for each of the three phases. Instead, a reference voltage space vector V s is produced as a whole, sampled at a fixed frequency, and then constructed through adequate timing of adjacent nonzero inverter voltage space vectors V 1 to V 6 and the zero voltage space vectors ...

A lot of people have a hard time converting between power and voltage in 50 Ω systems. The full derivation requires a little extra work because of the use of the root-mean-square value of a sinewave, based on its peak voltage value. Here's how it's done. The Table of Equivalent Voltages & Powers was generated using an Excel spreadsheet.

Op-Amp Adder and Subtractor - Op-amp is used to design a circuit whose output is the sum of several input signals. Such a circuit is called a summing amplifier or a summer or adder. Peak detectors capture the extreme of the voltage signal at its input. A positive peak detector captures the most positive point of the input signal and a negative peak detector captures the most negative point of the input signal.

Apr 02, 2019 · You might be amazed at this, but my dual base amplifier performs exactly as LTSpice projected. The test was to feed a 50 mV signal at 10 MHz to Channel A input. Output was 364 mV peak-to-peak, for a gain of 21 dB. This was pretty much as modeled in LTSpice. Next I ran a frequency sweep from 100 kHz to 30 MHz. What I want to do is measure the gain of the amplifier (Vout P-P / Vin P-P). .MEAS looks like the way to do this, since it can be set up to give peak-to-peak measurements. I don't think this can be done by displaying waveforms, as the results are only given as RMS and average values for voltages and currents. Jan 21, 2020 · Hello friends, I hope you are doing great.

Sep 28, 2016 · The detector loads the source stage, possibly increasing its bandwidth. The output impedance of the detector is relatively high, which is undesirable. The volume control puts an AC load on the detector causing distortion in the audio. The diode used has to be a germanium type or a hot carrier diode that has a low forward conduction voltage. The S5973 from Hamamatsu is a leaded Si PIN photodiode in TO-18 package. This device is designed for visible to near infrared light detection. Photodiode is suitable for violet laser detection and other high speed photometry as it provides wide band characteristics at low bias. Diodes conduct current in one direction but not the other.

In other words, we want a peak detector that holds the peak only for a short period of time. We accomplish this by adding parallel resistance that allows the capacitor to discharge. (This type of circuit is called a "leaky peak detector," where "leaky" refers to the discharge path provided by the resistor.)I would use an PGA instead of digi potentiometer ; that gives the signal to an Peak detector from whom the signal is passed trough an ADC and given the command back to the PGA.
