I honestly rolled my own (in VHDL) using OSVVM (for scoreboarding and reporting) because all you can get free online is AXI4s and lite, while I needed full AXI4. AXI4L is just a restricted version of AXI4 but functions the same. My AXI4L entity is just a wrapper around a full AXI4 master BFM. I also use ActiveHDL with a sole VHDL licence and it is
Hi, We need a rough voltage bus of 300V, 900W (250V-350V is fine) Vin is post PFC bus of 380VDC We wish to use a ICE1HS01G based LLC resonant converter. The loads are multiple 20W led lamps which are fixed power but occasionally dim up and down. With such a high Vout, then considering all loads suddenly turn off (sudden no load), then we antic
need help with metal detector circuit if i use arduino/PIC micro controller ADC channel. 156811 if i want to switch the coil inductor at high current using mosfet for greater depth. because direct connection of switching signal from arduino pin is not the correct way for switching at high input current. and to use ADC c
Hello! I tried to write my own code for 2 push buttons to rotary encoder (UP/DOWN Quadrature generator) I have flashed it (ofcourse with changed ports) on PIC16F648 and it works perfect, it also works perfect in Proteus simulation with PIC12C509 (C509 was the closest i have to F509). The problem comes when i program it on real PIC12F509 - the c
We are using load switch and current limiting resistor to charge supercap from 5V, As we have 3.3V available at source we convert it to 5V using boost converter to charge supercap till 5V to get more backup time. 156840 We are using FPF2125 switch to protect reverse current flowing from supercap to power supply when po
Is anyone aware of a complete detailed description of the older commercial CMOS manufacturing processes, something between 1um to 2um node? There a lot of simplified process flows out there, and each of them appears to skip different steps. So I could not find an exact answer on some of the question, e.g. at what point they started adding LDD, cha
Hi Recently working on an Arduino based AC heater controller, I have been facing some unusual problems with MOC3020 and triacs BTA136 or BTA41. Attached, please find the schematic and the completed PCB. Initially, for testing, I connected an incandescent bulb across heater terminals and connected the FIRE pin to 5V. The bulb lit fine. A
STM8S001J3 is an 8-bit microcontroller that offers 8 Kbytes of Flash program memory, plus an integrated true data EEPROM. It is referred to as a low-density device in the STM8S microcontroller family. This MCU offered in a small SO8N package. In this
Hello Everyone Would you please help me in this problem. I am using Orcad Cadence 16.3 to simulate AC-DC Flyback circuit, everything is good when I simulate the circuit in the open loop test, while moving to the closed loop when I try to run the simulation to a short time like 0.2s everything is good, but this time in not enough to see the stea
Additionally the probe "loop area" (between tip+shaft, and ground clip) is an inductive pickup for all the inductor leakage field, and your choice of ground- point embeds more or less I*R, L*dI/dt voltage noise from circulating ground "plane" currents to what the 'scope channel sees. Output filter wants low ESL/ESR, but the inductor also contr
Because the subthreshold slope has not intersected the junction leakage floor by the time you hit Vgs=0. This not only makes the leakage higher, it makes it highly variable - a nominal 80mV/decade means that if your VT of 200mV (low-VT) has a +/-100mV tolerance the real leakage current could vary upward by over a decade at Vgs=0 (or downward, bu
First of all yes it is homework but I worked on it and stuck at only this part. Maybe I am approaching on wrong side I am open to every advice. I need to design a environmental noise checker circuit. I am not allowed to use any IC except OPAMPS! Passive elements (resistors, capacitors, inductors, diodes), leds, Analog Microphone, DC Power Supply
hey I have a simple setup with P32MZ2048EFH144 It has no external oscillator. I have a simple code with Delay_ms(1000) which appears to work fine (the led blinks at about 1 second) But.... I think there is something I dont understand. Take a look: 156716 No matter what I set in "MCU Clock Frequency ", the blinki

Hello all, First of all, I apologize for evey mistake or blunder I make within this post but honestly its my very first time here ;-) Problem that I experience it kind of hard to explain but I will try my best. My employer wants to make a simulation when few transmitters with the same waveform (modulation, coding scheme etc.) operates in given fr
Hello friends volatile variable indicates that an object may be changed by something external to the program at any time and so must be re-read from memory every time it is accessed. we can use volatile variable in interrupt #include #define led PORTD void main(void) { led=0; TRISB0=1; TRISD=0;
Depending on how sensitive you are to things like power and timing symmetry and channel count, this could be a single "logic level" PMOSFET and a resistor load to -5V. But hogs power half the time and transitions would be pretty sensitive to loading.
In fact there is no "CMOS transistor" - there are NMOS and PMOS. As a rule "RF guys" appear to prefer the zero-VT device for gm and IDsat, relative to capacitances. You can find canned NMOSFETs for lower frequency applications. Anything over maybe 1GHz probably wants integrated transistors. Kind of wasteful for a 1-transistor LNA (study p
