Figure 1 demonstrates a one-way switched-capacitor gain stage circuit, performing a voltage gain of AO = ­C1/C2 only during the decreasing trail of the input signal Vi (with VJ... After the reset ...
An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...
To sense animals moving I wanted to create a simple IR sensor that would trigger a monostable to generate a rather long pulse when an animal passed by. Further, while the animal remained in front of ...
