Feedback Topologies

This is my homework problem. I tried to solve this problem but i got it wrong. Here is the problem: As it is clear from the circuit that we are taking voltage at the node V0 and some fraction of output voltage is feeding back into input. So…

How is circuit topology chosen in analog designs?

Suppose I'm an experienced analog designer, e.g., RF, power electronics, ADC. How does choosing a circuit topology fit into the overall workflow for a typical work assignment? I imagine my manager will be responsible for a larger system, like a…

Unknown DC-DC converter topology in ST datasheet

I have found this weird DC-DC converter topology in datasheet of MC34063 from ST. The primary charging is single ended, so at first it seems like flyback, but it has four diodes on the output instead of only two. Is this some forward or flyback…

Linearizing multi-star network for home automation

I'm designing a communication network for private home automation. My design goals are: Local wrt network changes. That is, changing one part of the network should not require modification of the network as a whole. Easy to use. Adding or removing…

How to select DC-DC converter topology?

I would really appreciate some help on this one. I am doing my bachelor's thesis/project which requires me to design and construct a DC-DC converter. I have been working on it for a couple of weeks now. My main issue is justifying the selection of a…

What is an integrator topology?

I'm a hobbyist building lamps using Arduino's, LED lights and MOSFET's. A few times now I've seen a reference to "integrator topology," also in relationship to diagrams with MOSFET's in them. They seem to relate to what I'm working on so I'd like to…

I2C differential network architecture using PCA9615

I'm building an architecture for a large scale robot (3x3meters) and I would like to build a specific architecture around I2C differential to control motors drivers (this should be noisy). My problem is, in order to avoid high cost cables and…

2KW - 48V - 240v / 50Hz UPS - Unknown Topology

I am refurbishing a 2kw ups that a friend gave to me. It had failed and had been left in a shipping container on a site and the PCB had suffered some low level corrosion. The PCB is a 2 layer board, all through hole main power circuit stuff is on…

Designing a CANbus+DC power network of sensors

I'm designing a network of sensors to be placed in an outdoor environment, see the attached diagram. The network will consist of 30 data acquisition boards (very low power consumption), divided in 10 zones ("Silo bags" in the image). Each zone will…

Is there a name for this transistor configuration?

The transistor configuration found in the schematic below can be used as the input to an op-amp that can work with a common mode input at or above the high supply rail. For example this configuration appears in the design of Analog Devices' LT6015…

Advantage of the very common electronics-lab.com linear power supply circuit

I'm in the process of designing my own lab power supply. During my research I came across a design from electronics-lab.com that seems to be very popular for DIY adjustable power supplies (here is a forum topic with over 2000 replies!). This is the…

Circuit topology name and function for PNP transistor in light barrier circuit

I have seen this rather simple circuit for end position detection of a DC motor drive mechanism. An infrared LED (V402) and a phototransistor (V401) are used as a light barrier. Can someone give me a hint concerning the circuit topology name and…

Topology of a non-inverting op-amp with bias

I have been trying to decide the best single-supply non-inverting op-amp topology to use the ADC of an ATmega uC for capturing the signal coming from SCT013-030-0-30A-0-1V split-core current transformers. The rated output of the sensor is 1 V, so…

Optimal topology for high-power small factor SMPS

I'm trying to design a relatively small and compact SMPS for an output rating between 200/300 W (400 V in and 20 V out). The AC input from mains is rectified and filtered and fed to a PFC boost stage where the output is around 400VDC. Then the next…

Two different topologies for flyback

I heard someone say the QR (quasi-resonant) flyback has a smaller primary side current than an ACF (active-clamp flyback) under the same circumstances. Is this correct? I tried to search for comparable tables between QR flyback and ACF, but I didn't…
