EMG Sensor Performance Analysis Using LTSPICE
Budget: $30 – $250 AUD
I'm seeking an experienced professional in LTSPICE simulation to carry out a thorough performance analysis of an Electromyography (EMG) sensor.
We need a comprehensive LTspice simulation of our wireless EMG sensor schematic. The design includes a LiPo battery, a battery charging IC, a flip-flop CD74HC for device activation via a pushbutton, an antenna, USB-C for charging and programming through an FT232RL, and data acquisition from three electrodes. These electrodes' signals are summed using an LM7301 active summing op-amp, followed by amplification with an AD829 op-amp, with the output directed to an ESP32 ADC pin.
The simulation should include transient analysis to verify signal summing, filtering, and amplification functionality; noise analysis to ensure low noise levels at the output; and AC analysis to evaluate the frequency response and confirm the circuit operates within the desired bandwidth (10 Hz to 500 Hz) for EMG signals. I'm specifically looking for a high signal-to-noise ratio, and I need you to ensure that the sensor meets or exceeds this requirement.
Ideal Skills:
- Prior experience in EMG sensor design and LTSPICE simulation.
- Strong background in circuit analysis, signal processing, and analog electronics.
- Ability to interpret simulation results and provide actionable insights for sensor optimization.
