Voltage Level Translator
Basic voltage level translator utilizes a voltage comparator to translate an input voltage range into an output voltage range. First step is to determine the input voltage range, which involves an input low voltage level VIN(low) and an input high voltage level, VIN(high). Next step is to figure out the proper reference voltage level, at VREF. In many cases VREF can be simply midpoint between VIN(low) and VIN(high). In other cases, one may want to skew the VREF voltage level towards either VIN(l

However, at low operating voltages, the values of the resistors and the impedance of the inverter MOSFET are selected to optimize oscillation stability and at the same time minimize power consumption. Using the appropriate component values, a LC circuit can be configured to opera

Basic EPAD? MOSFET Connection with Current Source Drive
This circuit shows a basic diode"connected MOSFET connection driven by a constant current source. The drain terminal is shorted to the gate terminal. When connected in this manner, this circuit produces an output voltage VO. The drain current Ids that flows through the MOSFET increases exponentially with increases of VO, with Ids vs. VO characteristics similar to that of a forward biased diode. Hence the term œdiode-connected configuration. This type of circuit is very useful to clamp or

Zero Crossing Detector
This circuit is a zero crossing detector, which produces an output state change whenever the input crosses the reference input. In this case the reference input is connected to ground. The output of the comparator can easily drive multiple outputs, which can include, for example, a relay, a control gate and a LED indicator. Note that this circuit works with either open-drain or push-pull types of comparator output, depending upon the load(s) to be driven. The load, in many cases, can also act as
Micropower Buffered Rail-to-Rail Adjustable Voltage Source
This circuit is a variation to the basic connection of a unity gain buffer amplifier. The unity gain amplifier is used primarily to isolate the input from the output. In this configuration, the output is connected back to the negative input terminal of the amplifier. Therefore any voltage at the output would be forced upon the "ve input as well. As the operational amplifier has very high open loop gain, the output voltage would tend to be forced to a value very close to VIN voltage. Any dif
