log amplifier and antilog amplifier

I have some problem with this circuit, the summering is not right and I should get 8 voltage at the output, but get 13.968 V. I need some input to solve it. Thanks for your help. I use LTspice, to simulate.

pros and cons of replacing a passive inductor by a gyrator

I am studying the construction of some touch sensors, and I need inductances of 10mH, I know I can easily do it, and also purchase them without much difficulty, however I know that it is possible to simulate such inductances using a circuit called…

Floating Simulated Inductor

In the image below, I do understand that a grounded inductor can be simulated using op amps. However, to make a floating simulated inductor, I have read some posts that said two ground simulated inductors must be connected back to back. I am not…

Simulated inductor for guitar use

Edit: Sorry! Please bear with me, this is my first post! Well, it seems that placing a buffer before certain fuzzes can chance their sound. However, placing an inductor after the buffer cancels this effect ("unbuffers"):…

PIC24FV Reset without Flag

I am working on building an interrupt based program flow using the PIC24FV32KA302 module from Microchip. However, I am having some trouble with intermittent resets (it seems). I am currently using the MPLAB X Simulator, trying to find out where the…

LTSpice - Capacitor Charging/Discharging Circuit not working right

I am trying to do a charging and a discharging Circuit. R8 is the load that Capacitor C1 needs to discharge into when P12V_IN is low. My question is Why is Vsolenoid low in the interval shown on the waveform when P12V_IN is low? I am expecting that…

Confused about this simple Comparator Circuit Output Waveform

Below is my Circuit and Voltage Waveforms for the Comparator Circuit. My question is -- In the Highlighted area in the waveform - why is the V(CMP_OUT) not high since inp_u2 (blue) is higher than inp_u1(green) for this interval? My goal is that…

LTSpice - Voltage Comparator not working

My question is - why is CMP_OUT not going to HIGH (i.e. to 12V, P12V_IN) when INP_U1 is greater in voltage than INP_U2. I think I haven't wired the LT1011 right. Do I have to do anything with the "B" and "S" pins? I am open to using another part for…

DC sweep analysis not matching transient analysis for amplifier

I'm building a little sound amplifier for something and can't quite understand why it's not a powerful as I though it might be. This is the circuit, and a simulated DC sweep is shown below:- Vdrive is the meeting point of the output transistors Q1…
