Hello,
I want to develop my own microphones for audio recording. Once I get the schematic, how can I simulate the microphone performance?
Can I use something like Altium, ADS or HFSS?
Hope someone can help me
Best Regards,
Sebastian
I'm using an LM61. It's an analog sensor. But none datasheet specifies the equivalent resistive load of the component.
I dont think I can measure that with simply a multimeter, did I?
What would be the equivalent load of a Temperature sensor? or how can I measure it?
Can I assume an equivalente 1k Ohm load for a WSN?
I need this value to design a rectifier. I'm confused, hope you can help me.
I harvest energy from the ambient, then charge some capacitors and finally discharge them to read a temperature sensor and send the data to a Monitoring Node to plot them in the web.
Due to the charging time of the capactiors, the data can be sent hourly.
I need to justify why this would be a...
Good Morning,
I'm working in an Energy Harvesting system to power a Wireless Sensor Node, due to low efficiency of the system, I'm able to send temperature measurements every hour (or half hour) and plot it in a Internet Server.
My question is, what would be a real telemetry application where...
This is the schematic, hope you can help me.

Would be like this schematic, but whit a different Impedance mathching network. My Mistake...
Silly question here: Can you explain me how to conect the output of the rectifier?
I'm so confussed, because whit this design I got an output current over the load, but how do I conect that to the next stage?
I understand Vout would be in the out of D4, but the out of D3 would be the ground...
Thanks, that make absolute sense. Off coruse, I dont need to put the resistor in the PCB, I'll waste all the energy...
The rectifier supply a boost stage, a MCU and finaly a RF Transmiter.
Can I asume the modeled load is equal to the actual load?
Thank You both.
Here I attach the Schematic.
The output of the rectifier it's conected to a boost and storage stage.
The PCB is FR4. And the project is for Energy Harvesting.
I'll apreciate any help.
I designed an RF rectifier and I found that a 10k load increase the efficiency for my design.
In the PCB, do I have to put this 10k Resistor? or just conect to the rest of my circuit?
Hope you can helpe me!
Silly question here,
I designed a rectifier and an impedance matching network for RF energy harvesting.
The impedance matching network needs a ground plane in the bottom layer. Currently, this ground plane is only behind the matching network. If I extend it to be under the rectifier section...
Good Morning,
silly question here.
In this RF rectifier, PORT1 corresponds to an antenna to harvest energy from ambient. Are, the antenna ground (green) and the rectifier ground (red), the same? I mean in a PCB i have to connect this two grounds?
I'm guessing that for the simulation I don't...
