x^n power function returns real values only 01

x^n power function returns real values only 01 PUBLIC

It is not made clear in the CL Documentation for expressions: https://www.circuitlab.com/docs/expressions/ but the ^ or POW(x,n) function only returns the real part of x^y. This means that it returns...

behavioural ADC - DAC blocks 01

behavioural ADC - DAC blocks 01 PUBLIC

CL does not provide an explicit A to D or a D to A function. This describes two variants of a very tedious way to make a block that quantises an input voltage like an ADC and produces an output...

SOA demo 01

SOA demo 01 PUBLIC

An example of a circuit where the Safe Operating Area (SOA) of a device (M1 in particular in this example) is exceeded at some times and not at others. This is to illustrate the complexity of trying...
