This is an ultra-low supply voltage LC (Colpitts) oscillator circuit using EPAD MOSFETs with passive resistor load and output buffer. This circuit is similar to a classic LC oscillator circuit used to power 5V circuits. 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.

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

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

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

This circuit presents a simple precision DC summing amplifier that has high input impedance of 10Mohm. The obvious advantage is that the 10Mohm high input resistance of the summing resistor(s) reduces the loading on the input signal sources and therefore affords better signal accuracy and integrity. The input leakage currents to the operational amplifier must be significantly lower than the lowest input signal currents available so that the accuracy of the summing amplifier is preserved. In this

The output buffer is powered by ROUT, which can be selected to optimize the output voltage swing levels as well as providing adequate output
