2019年12月1日 · Strictly speaking, in the "emitter resistor case", the emitter is not common; the lower end of the resistor is common. So this configuration is not "common emitter; it is sooner …

2022年7月13日 · \$\begingroup\$ Yes, that is true. Increasing RE and simultaneously increasing the base bias (and emitter bias) to keep Ic (and re) constant does indeed reduce collector bias …

2023年12月29日 · How I calculated the resistor values: I assumed that Ic = 1mA, and β = 50.5. It is given that VDD = 5V and to design the circuit to get a gain of 10. The transistor is 2N4401 …

Some authors say the frequency must be the lowest frequency, below which, I want to remove from the signal. Some say it must be the highest frequency the amplifier must amplify. I am …

2013年3月12日 · The final audio amplifier circuit is therefore: C1 attenuates components of the input signal from about 20 Hz down, and completely blocks DC. You might want something …

2023年9月23日 · I have the following common emitter amplifier circuit. I am also told that, when taking the specs above,to consider a 20% safety margin to accommodate for possible …

2015年3月29日 · The gain of a small signal transistor will be at least 100 so if we take the current flowing through R1 and R2 as about 1/10th the collector (or emitter) current, When the …

The circuit is pretty much standard, well understood and lends itself to a simple analysis. Let's start with the value of emitter resistor (R4). The voltage across it should be between 10 and …

2024年5月30日 · Both answers describe the output impedance of a common-collector amplifier, but I don't understand 1) how this applies to finding the gain of a common-emitter amplifier like …

2020年5月31日 · The input peak level is 500 mV so it is being over-driven but the tuned circuit does a good job of restoring the sinewave shape. I don't think you can "adequately" achieve …
