91. A two-way mirror - current mirror that is
    Stephen Woodward
    Circuits Texas Instruments LMC555
    One classic set you’ll see in most гvintage mystery movies is an interrogation room with a “two-way” mirror in one wall. This cool gadget lets the witnesses see the suspects from another room while the suspects can see only ...

93. Another PWM controls a switching voltage regulator
    Christopher Paul
    Circuits Texas Instruments SN74LVC2G14 SN74LVC14A TLV333
    A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators”( Reference 1 ), demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were some discussions in the ...

97. A simple circuit to let you characterize JFETs more accurately
    Cor van Rij
    Circuits Texas Instruments TL071A
    In April 2012, EDN published a circuit by John Fattaruso ( Ref. 1 ) that lets you quickly measure the drain-source saturation current and the pinch-off voltage of both an N-JFET and a P-JFET. The pinch-off voltage (V P ) is measured by inserting a ...

98. Converting square-waves into saw-teeth
    Stephen Woodward
    Circuits Texas Instruments CD74HC4053 TLV2371
    Generating analog sawtooth waveforms (linear ramp followed by a quick reset to zero) from digital timing signals is a common function. It usually requires a negative supply as sketched in Figure 1, where Negative current through R1 ramps up ...

100. Circuit delivers constant power to a load
     Kiril Karagiozov
     Circuits Texas Instruments NE555
     If you have a load with a variable or poorly specified resistance and want to regulate the power applied to it (a heater for example), merely controlling the voltage or current will not work, as in both cases the power P = I 2 R = V 2 /R depends on ...
