I'm trouble shooting a circuit for an R/D converter. One circuit is an op-amp booster. It takes a sine wave in differentially and drives it single-ended. It uses a booster stage to drive the signal at 10V peak. I'm not familiar with booster circuits using transistors. Can anyone tell me if...
Is there a way to calculate the ideal resistances required to properly design a simple transistor switch? Let's take an NPN low side switch with the emitter grounded. The circuit has an input resistor (Rin) from an external input and a resistor from the base to ground (Rb) to hold the...
First of all, thanks for the help on the AGC circuit post. The problems I was having were in the RF path, not the AGC path. Circuit works fine except...
I need a dead band circuit. I want to ignore the output of the detector until it gets to about 0.5 volts, then bring the ACG into play...
This is my first time designing an AGC amp for an RF application. I'm using a commercial AGC amplifier and detector (Teledyne Cougar). The AGC amp has a 0-5V control signal, 0V is full gain. The detector has a 0-5 volt output. 0 volts occurs at -40dBm and 5 volts at +10 dBm. I want the output...
