It looks like you are using a Transient Analysis -- that is not the type of analysis that you should use to see the Frequency Domain characteristics of a circuit. Have a look at this article, and let us know what a better SPICE analysis mode would be...PhysicsTest said:TL;DR Summary: Understanding the phase delay
I simulated the below circuit to capture the phase delay between input voltage and output current in LTSpice
PhysicsTest said:I am analyzing the circuit and will come up with the exact problem i am facing.
More accurately, a square wave will start to charge up a capacitor with the initial application of the first pulse. Subsequent pulses alternately start to discharge it and recharge it... (see the OP's transient SPICE simulation):osilmag said:A square wave will charge a capacitor up as soon as it is applied
Phase delay in a circuit refers to the time difference between the input and output signals of a circuit. It is caused by the reactive components in the circuit, such as capacitors and inductors, which store and release energy at different rates.
Phase delay is measured in degrees or radians. It can be calculated by dividing the time delay by the period of the input signal and multiplying by 360 degrees or 2π radians.
Phase delay is caused by the reactive components in a circuit, which create a phase shift between the input and output signals. This is due to the fact that these components store and release energy at different rates, causing a time delay in the output signal.
Phase delay can affect circuit performance in several ways. It can cause distortion in the output signal, making it different from the input signal. It can also affect the frequency response of the circuit, leading to changes in the amplitude and phase of the output signal.
Phase delay can be minimized by using components with lower reactance values, such as capacitors with higher capacitance and inductors with lower inductance. It can also be reduced by using active components, such as op-amps, which have a high input impedance and can compensate for the phase delay caused by reactive components.
