    Output logic source and sink

    Hi all, Im working to design a circuit that can sink after a load is apply, but when there's no load also be able to output logic levels 5v/0v. The max that a load could be is 12V and not not more than 100ma, therefore I decided to use octocapulers to make some output logic. In my attach image...

    Hardware Interlock Circuit with AND & NOT Gates

    Here is my Hardware Interlock Circuit for Gate Signals which prevents both PWM Signals to be at same state at any given time. Here I want to reduce this two AND Gate IC's into a Single AND Gate IC. Or Is there any other way to implement the Hardware Interlock for Gate Signals ? Is there any...

    I need some help with my assignment, because i am not an expert...

    Basically assignment was to create a counter using JK triggers and the 7 segment display should count down from 13(d) to 0. Problem i am facing with is that i made this scheme with parallel transmission, but i need to have sequential transmission. Can you help me with that? Also if i press reset...

    Asynchronous counter that counts from 0 to 13

    Hello everyone. I'm having troubles with my homework. This is the description: The aim of the assignment is to design an asynchronous counter that counts from 0 to 13. Design assumptions: The counters should be asynchronous and implemented with flip-flops and logic circuit gates. • The...

    Did someone know how to make this SAR ADC 5 to 4 digital error correction circuit

    DEC1 is similar to half adder , b<K> is number of the SAR output code ,DEC2 is like binary caculator keep carry , but how to do this circuit ?

    ExpressSCH Netlist Error Regarding NetNames

    Hi, I am having a hard time figuring out how to fix this warning. It says that that symbol '0v' is connected to a net with two different NetNames. It refers to the other symbol located on the upper right which is 'Vpp'. It tells me that I need to change the name or remove the symbol at all. I...

    Auto increment I2C addresses for PI4IOE5V96224ZLEX

    I am using PI4IOE5V96224ZLEX for one of the project. It's a stackable I2C design, each stack shall have common hardware and will be stacked one upon the other. The base unit shall have an MCU which shall act as I2C master, while all other stacks as I2C slaves. PI4IOE5V96224ZLEX datasheet...

    Microwave detection circuit verification

    Dear all, I want to develop a circuitry which is able to detect electromagnetic waves(radio-wave , micro-wave). This circuit will just act as a tamper detect and not physically measure/compute the radiation. I have designed the circuit using toroid ring and few Schottky diodes. The calculation...
