  1. The easy way to clamp a signal to a given value is to use two zener diodes, connected back-to-back. This method has several disadvantages. The accuracy of the clamping depends on the tolerance of the zener diodes, and the clamping is not ...

  2. Circuits Automation Supply Maxim MAX6605 MAX4402 MAX6003,
    Fan noise is becoming a significant issue as electronic equipment increasingly enters the office and the home. Noise is proportional to fan speed, and the airflow hence, fan speed necessary for cooling is less at low ambient temperatures. Because ...

  3. Circuits Analogue Design Power ON Semiconductor MC33072 PN200A BD135G BD136G
    P-channel MOSFETs can simplify designs when you use them as high-side switches on circuits with voltages exceeding 100 V dc. When driving a MOSFET, you must rapidly charge and discharge the input capacitance between its gate and its source to ...

  4. A designer who uses a phototransistor to convert a modulated optical signal to an electrical signal frequently encounters problems when high-intensity background light saturates the phototransistor. When its base terminal floats, a ...

  2. EDN The circuit in Figure 1 provides 32 steps of brightness control from 0 to 100% for a backlight or instrument panel, using just two general-purpose-microprocessor signals. In addition, the circuit requires little board space, because it uses ...

  3. Although the prevailing number set in electronics is binary, human-machine interaction uses a decimal-number set. For this reason, designs often require the use of amplifiers with gain programmable in steps in the power of 10. Currently, Analog ...

  4. EDN Test equipment for a production line should be user-friendly (read “idiot-proof”) and should offer minimal test time. In many cases, the test fixture must give an operator only one answer: pass or fail. Usually, two indicators ...

  5. EDN The simplest technique for measuring current in an actuator or a motor is to monitor the ground current with a resistive element between the load and the ground. Because the device and its associated electronics share a ground potential, you ...

  6. Electronic Design In this Idea for Design, using a comparator-based switch-mode driver circuit of a solenoid improves efficiency by tailoring the drive to the pull-in versus hold-mode current requirements. Several years ago, Paul Rako, in ...
