I have build a differential amplifier comparator and it works fine except that instead of switching voltage between zero and 5v, it toggles it between 3.5v and 5v.
So, I would like to know if there's a way to make it switch between 0-5v.
The schematic is as follows
I need some clarifications for a non-inverting comparator design. I am using TLV7031 from TI.The circuit configuration is given as shown.
In the datasheet it is given as " When VIN is low, the output is also low. For the output to switch from low to high, VIN must rise to VIN1 ".
Here's a circuit i've designed for measuring approximate current flowing through a mosfet. I have a uC that has no ADC, it only has a comparator and an internal bandgap reference voltage. So i can't just connect the drain to an ADC input and divide the voltage by Rmosfet.
The line marked "PWM"...
I have designed a low battery detector circuit using low power comparator MCP6541 for a 4.2V Li-ion battery. This circuit checks whether the battery voltage if the battery voltage is lower than 3.5V then it will glow LED. Check the circuit below.
The circuit is working properly but the...
i am trying to get a comparator working with Hysteresis. A 500mV is the target between Vlth 2v and Vhth 2v5.
Can somebody please help me with the Hysteresis part with an explanation for the attached LTSpice simulation.
How to make a full bit (2bit) comparator circuit using ONLY nand gates. I was able to do a 1bit comparator using only NAND gates, but how about for 2 bit, 4 bit? Wouldnt it be really large. I'm not sure if my class expects us to draw this out. we can't even use xor gates or inverters.
