Circuit Simultaneously Delivers Square & Square Root Of Two Input Voltages -  03/01/12  EDN-Design Ideas - Use a common CMOS gate to make long duration timers using low-value RC components.  The CD4011 CMOS NAND gate has a typical input current of 10 PA at room temperature.  You can charge a capacitor connected to the gate input with currents on the order of hundreds of picoamperes and neglect the influence of the gate-input current on the charging time of the capacitor.  You normally need large-value resistors to limit currents to this low level.  These resistors are not commonly available.  You can instead use a transistor as a current attenuator, despite its more usual amplifying nature.   __ Circuit Design by Marián Štofka, Slovak University of Technology, Bratislava, Slovakia

Circuit takes square root of input voltage -  11/20/97 EDN-Design Ideas - For an NMOS transistor operating in the saturation region, the relationship between the drain current, ID, and the gate-source voltage, VGS, is governed by the square-law equation __ Circuit Design by Mark Shill, Burr-Brown Corp, Tucson, AZ

Square Root Function Improves Thermostat -  09/30/99 EDN-Design Ideas - Perhaps the most elementary rule of control-loop design theory is that feedback-loop performance is fundamentally linked to the careful choice—and stability—of loop gain.  Insufficient loop gain leads to poor setpoint accuracy.  Too much gain can induce feedback instabilities,  __ Circuit Design by W Stephen Woodward, University of North Carolina, Chapel Hill, NC

Square-Root Circuit -  This circuit generates the square root of the input at a reference voltage.  Such type of square-root output is normally used in R&D labs.  Fig.1 shows the proposed circuit.  A sawtooth...__ Electronics Projects for You
