On the circuit below, the load resistor has been replace by a tuned circuit, C4 and L1. The tuned circuit is high impedance at resonance. The impedance is low at all other frequencies. Therefore, the signal which is amplified only at the resonance frequency. Since this type of amplifier is normally used in RF application, the capacitors can be much […]

As far as AC is concerned, the base is connected to the ground by the C3. Therefore, both input and output are connected to the base (common base amplifier). The magnitude of the current gain is less than 1 since Ic/Ie. Since it is Rc/Re, the voltage gain is high (approximately the same current flows through them) and it’s typically […]

Current mode amplifier has the benefit of higher frequency operation, and LM359 comes as operational amplifier with this type op amplifier. Current mode (Norton) amplifier can be used in video, RF, of high speed communication design. You can apply this current mode noninverting amplifier in wide variety of applications, make sure this circuit performance (shown as the frequency response curve) […]

Balanced signal consist of two lines that have opposite phases, and should be received with differential input receiver. Balanced signal is employed in many telecommunication techniques to improve transmission system’s noise immunity. Balanced signal is usually transmitted in twisted pair cables. With twisted pair, the noise exposure is expected to be equal for both lines in order to cancel each […]
