    Circuit with Variable Load – Switch-Induced Spikes When Changing Load

    The circuit is a combination of two Improved Howland Current Pump subcircuits, alternated by two switches controlled by a voltage (Square Wave 0-4V), with two electrodes as a variable load (1-1kΩ). Everything works fine, except for the presence of spikes caused by the activation of the switches...

    Resistor and capacitor order dependent noise in the output signal (measured with a handheld oscilloscope) of an RC circuit

    Hi. I have an RC circuit 1kOhm and 22uF that generates a sine wave from a PWM signal generated by a battery powered STM32F103C8T6 (Blue Pill). I take all measurements with a handheld oscilloscope (battery powered). The PWM frequency is 10kHz. I noticed that the connection order affects my...
