I half understand the Arduino Uno power select circuit that uses as p-FET to disconnect the USBVCC when an external Vin is supplied, but one bit baffles me. If no external supply is connected then at startup what state is the p-FET in? If the p-FET is ON (Vgs -ve) then USBVCC ...

通过所有这些组件,接收器接收来自天线的信号,然后通过射频调谐电路进行调谐,并使用 OP-Amp 放大这个微弱的信号,并将这个放大的信号进一步用作 PLL 的输入,从而使解码器锁定到输入的数字位上,这会产生噪声较小的输出。 调制: 调制是将数据转换为电信号的过程,这些调制后的信号用于传输。我们调制信号,以便我们可以将必...
Hi, I have the circuit connected as shown above. Both CC2541 and Arduino are getting the SAME input analog voltage at the ADC input. They both have equal ADC reference voltage. However, when I look at the data in my laptop, I see that the CC2541 AD...
To enhance the resolution of current measurements with the ACS712 sensor, you can amplify the sensor’s output signal using an operational amplifier (op-amp) circuit. This can help increase the sensitivity and precision of the current readings. ...
A simple differential amplifier, realized with an op amp, is used to remove the 0.55 V offset and to amplify the output signal in order to reach the desired value. The following figure shows the scheme of this circuit: To generate the voltage Vp = 0.55 V, that is, the minimum value of...
