Distortion in rc coupled amplifier

AI Thread Summary
The discussion centers on issues of distortion in an RC coupled amplifier when a 50mV sine wave input is used. The distortion may be caused by excessive input signal levels or incorrect biasing of the amplifier. Participants suggest posting a circuit diagram for better troubleshooting. The user confirms that the output signal appears non-sinusoidal when viewed on a CRO. Proper circuit configuration and biasing adjustments are essential to mitigate distortion in small signal amplifiers.

hi,
when i was making a rc coupled amplifier but as soon as i connect the input signal the signal gets distorted.can anyone tell me the reason for that and how to avoid the distortion?

thanks,

Yes, you might be driving the amplifier with too much signal, or you might have the bias wrong.

Post a diagram of your circuit and it may be possible to see what is wrong.

How do you know it was distorted? Were you trying to drive a speaker with the output?

no. actually i was making a small signal amplifier to understand the working of it.i fed a sine wave of 50mv and connected the output and input to CRO.it shows that input signal is not at all sinusoidal sine.

thanks for paying attention.

Can you post a schematic of your circuit?
 

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'

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...
