  1. For a recent design project, a robust power supply was needed to control the gates of high-side FETs. Optocouplers readily translate the logic signals up to the correct control voltages to drive the FETs. However, to ensure that the FETs turn on ...

  2. This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a similar resistor-FET-logic. Further, ...

  1. Low-cost monolithic precision adjustable voltage references are available in multiple families from multiple manufacturers, but this isn’t true for adjustable precision current references. That’s unfortunate, because while most ...

  2. Self-powered isolation amplifiers, which need no external isolated power supply, provide versatile and convenient interfaces in many applications that require galvanic isolation of the signal source. Examples of such applications include circuits ...

  3. LED drivers have lots of features and require plenty of external components. When your application requires no PWM (pulse-width-modulated) dimming or controlled frequency operation, your primary concern may be that too much current could damage or ...

  4. Besides its mind-boggling simplicity and programmable resolution, the chief attribute of the Shannon decoder DAC (SD) is speed ( Ref. 1 ), converting a serial n-bit digital stream into an analog signal in just nT seconds where T = 1 bit time. Of ...

  5. Introduction A 500 V protection circuit for low voltage high impedance measuring instruments is shown in Figure 1. The protection is accomplished by limiting the amount of current going into the measuring instrument. The circuit will protect ...

  6. Piezoelectric buzzers find wide use as audible-signal generators because of their low power consumption and clear, penetrating sound. An external driver or a self-driven circuit that oscillates at the resonant frequency of the piezoelectric element ...
