Nov 4, 2025 · In the blogging world, there are different kinds of blogs and bloggers who blog to reach specific goals. 52K subscribers Subscribed The gain-boosting technique [Fig. 3. ) 8. 13. Then you will implement a similar circuit using a non-inverting op-amp. Determine the expression of the output current lout as a function of Irer if the transistors have the following sizes: W/L:W/Ly;W/L3; and W/LA. Example Problems 1. Differential and common mode voltages: v1 and v2 are called single-ended voltages. Electron Devices and Circuits: Unit IV: Multistage and Differential Amplifiers BiCMOS Amplifiers Equivalent circuit, Solved Example Problems | Multistage Amplifiers Home | All Subjects | EEE Department | Electron Devices and Circuits Example analysis of MOSFET Cascode amplifier. 7=10. This configuration consists of a CS transistor feeding into a CG one. 8. . When designing an amplifier like this I really only care about a few things and don't always want to go through and calculate everything every-time. It also discusses the reverse gain of a cascode amplifier briefly. 73 The purpose of this problem is to investigate the signal currents and voltages at various points throughout a cascode useful in designing the circuit so as to allow for the required signal swings. When adding Cload to a single stage design, you shift your dominate pole to a lower frequency which increases your PM and makes your amplifier stable. i simulate it on lt spiece the gain obtained from graph is 4. However, if the FA is not properly designed, a low-frequency pole–zero frequency dou-blet will appear in UNIT – I BJT Amplifiers- Frequency Response: Frequency response of an amplifier, Analysis at low and High Frequencies, Hybrid-pi (π) common emitter transistor model, validity of hybrid- π model, variation of hybrid – π parameters, Millers theorem and its dual, the CE short circuit current gain, current gain with resistive load, gain-bandwidth product. 3a is an improved current mirror that increases the output resistance, providing better current copying. Jan 11, 2026 · This guide breaks down the most popular blog types, from personal finance and wellness to travel, food and business. Jul 4, 2025 · We’ve brought together the 25 best types of blogs that are popular in 2024 and have the potential for a consistent audience throughout. On this channel the Questions (and its video Solution) from different electronics subjects like Analog Electronics, Network Characterization of Current Mirrors current mirror is basically nothing more than a current amplifier. (Historical Note: the cascode amplifier was a cascade of grounded cathode and grounded grid vacuum tube stages – hence the name “cascode,” which has remained in modern terminology. The transistors used have β=100, ro=100kΩ, Cπ=14pF, Cμ=2pF, CCS=0pF. 5. 11. Political Blog. Apr 18, 2025 · In this guide, we’ll reveal the most popular types of blogs based on our decade of experience and analysis of thousands of successful blogs. Calculate the small-signal voltage gain, output resistance, the dominant pole, and the nondominant pole for the low-gain, cascode amplifier and the high-gain, cascode amplifier. 73 shows a CMOS cascode amplifier with all dc voltages replaced with signal grounds. 2. The Common Emitter input resistance is relatively high and Common Collector output resistance is relatively low. Jan 10, 2025 · After reading this, you can get ideas about the different types of blogs and the best one that suits your needs. Jan 22, 2021 · In this article, what is cascode amplifier, advantages of cascode amplifier and the effect of various load on the voltage gain is explained. 08K subscribers Subscribed In this video, what is Cascode Amplifier, and the small-signal analysis of the Cascode Amplifier is explained in detail. The cascade of a Common Emitter amplifier stage followed by a Common Collector (emitter-follower) amplifier stage can provide a good overall voltage amplifier, figure 10. Travel Blog. Derivation of the gain using the small signal model and by inspection. Oct 14, 2025 · In this article, I’ll break down the various types of blogs, show you how each type can be optimized for better SEO payoff, and help you decide which one is the best fit for your goals. Figure P8. 4kΩ. 77 = 131 Next, create the small-signal equivalent circuit for the amplifier and perform a small-signal analysis: Replace all AC coupling capacitors with shorts Large enough to look like shorts at signal frequencies Connect all a voltage regulator and fully integrated technology, applied in the field of voltage regulators, can solve the problems of increasing the material bill of the chip capacitor, consuming significant board area, and ineffective for certain loads, Jun 4, 2019 · ⇥ How to improve the accuracy of the basic current mirror? The accuracy of the basic current mirror is improved by the use of the Wilson technique (adding 3rd transistor), Widlar technique (emitter degeneration), or the cascode, each addressing certain accuracy problems such as base current mismatch.
