Download Article : Simple Circuit Measures Voltage-Dependent Capacitance.pdf There are many techniques for measuring capacitance. Some of these techniques require a function generator to provide either a sinusoidal or step-function voltage source. The design idea presented here has the advantage of requiring no special excitation source. Instead it relies on a simple test circuit, along [...]

Download Article : Low-Power Thermal Airspeed Sensor.pdf Among the techniques available to measure airspeed, thermal anemometry has the virtues of simplicity and easy miniaturization. Such anemometers use the relationship between airspeed and power dissipated by a heated sensor known as King’s Law. One good approximation to King’s Law is : S = A *[(P-D) / [...]

Download Article : Simple sine-wave generator has no low or high pass filters.pdf Generating sine waves with controlled frequencies over a wide range is difficult when using RC or LC sinusoidal oscillators. However, this performance can be simply created using a wideband digital square-wave oscillator, a counter, and a weighted summing network Using the circuit [...]

Download Article : Nanopower VFC Includes Self-Compensating Charge Pump.pdf Of the many starting points for voltage-to-frequency converter (VFC) design, one of the golden oldies is the classic diode-capacitor charge pump. An example of this fundamental circuit is represented by D1, D2, C1, and C2 (see the figure). Analysis of this simple topology reveals that each [...]

Download Article : Special Low-Pass Folter Limits Slope.pdf Adding several components to a simple first-order; low-pass filter; helps to create a different yet handy filter. The circuit shown in Figure 1 combines a low-pass filter (R2, C1, A1) with a bidirectional diode clipping network (R1, D1, D2). The result is a filter that will limit [...]
