    How to design a CMOS pll?

    In opposite to this question on designing a CMOS PLL, can someone redirect me to an article about a completely NON-CMOS PLL. Only discrete components or opamps please. I searching for technology of twenty years ago...seems scarce on the net nowadays. Thanks a lot on advance

    Analog PLL vs Digital PLL

    When you open a book about electronics there will almost always be a block-schematic af a PLL. What I really would like to find one day, is a circuit of an all analog PLL. With discrete components or opamps...no CMOS involved. Thanks

    Complex impedance calculation

    phase angle calculation from complex impedance What for range of frequency you thinking measure. » 3-50MHz how you think build measure bridge ??? » directional coupler + log detector power range? » depends on coupler...can go from 1mW...1,5kW Possibilities are infinite... Willy

    Complex impedance calculation

    degree-ohm You're right, the good old HP AN95, I've got to dig that one up... I'll break my brains on these maths again and then program a mcu to do the thinking for me :D Thanks, but still...all additional comments are welcome!

    Complex impedance calculation

    complex impedance calculator Hi, I found out how I can calculate the complex impedance of a unkown load by replacing it with two other loads and doing some maths, but what I´m really looking for is to calculate the complex impedance of a load by measuring forward and reflected power right...
