• ## bode plot tutorial using Matlab

[otw_is sidebar=otw-sidebar-1]         Bode Plot A Bode Plot is an important tool for designing and analyzing the circuits especially the feedback circuits. A Bode plot technique is based on designing and analyzing the electrical / electronic circuits in the frequency domain. This technique is named after the man who created it Hendrik…

• ## op amp input bias current and offset current

[otw_is sidebar=otw-sidebar-1]In this post op amp input bias current and offset current I will discuss about the input bias current and input offset current of the practical Operational Amplifier. In the last post I have discussed about the DC offset voltage of the Operational Amplifier and there I have mentioned that the practical Operational Amplifier…

• ## op amp offset voltage

[otw_is sidebar=otw-sidebar-1]In this post I will discuss about the op amp offset voltage DC imperfections of the Operational Amplifier. I have discussed in my previous posts that the practical Operational Amplifier does not exactly match the attributes of the Ideal Operational Amplifier due to which various problems arises in the operational of the practical circuit…

• ## Operational Amplifier as the Summing Amplifier

[otw_is sidebar=otw-sidebar-1]In this post (Operational Amplifier as the Summing Amplifier)I will discuss about the Operational Amplifier configuration as the Summing Amplifier. In the last post I have discussed the Operational Amplifier as the Programmable Gain Amplifier. I have mentioned there that the Operational Amplifier can employ to perform a variety of operations and the Operation…

• ## Operational Amplifier Active High Pass Filter

[otw_is sidebar=otw-sidebar-1] In this post I will discuss the implementation of the Operational Amplifier as the active high pass filter. In the previous post I have discussed the Operational Amplifier as the Summing Amplifier and we learned there that the Operational Amplifier can be configured to perform a lot of operations and the operation that…

• ## Operational Amplifier as Programmable Gain Amplifier

In this post I will discuss the Programmable Gain Amplifier based on the Operational Amplifier. In the previous posts I have discussed about the applications of the Operational Amplifier, ideal attributes of the Operational Amplifier, advantages of using the Operational Amplifier and a number of commonly used configurations of the Operational Amplifier. As mentioned previously…

• ## Operational Amplifier as Differential Amplifier

[otw_is sidebar=otw-sidebar-1]In this post I will discuss about the Operational Amplifier as the Differential Amplifier. In the previous posts I have discussed the applications of the Operational Amplifier, ideal attributes of the Operational Amplifier, some common circuits of Operational Amplifier. I have discussed about the differential amplifier earlier here I will consider it in detail.…
