    How to convert Square Wave to Sinewave

    For deriving sinusoid wave ,you'd better pick the filter type as Cauer (also be called as Elliptic) to reduce the order of the filter.

    Help designing a 10MHz square wave oscillator with very short Tr/Tf

    Thanks your guys. As i have little knowledge about microwave devices, i don't know if the point "The BJTs have an input capacitance of one magnitude lower than MOSFETs" is true. In my case, as well as a low input capacitance, the Cgd or Crss is another important term to be considered. So as...

    Help designing a 10MHz square wave oscillator with very short Tr/Tf

    Actually, it will drive a capacitive load, a MOSFET. The capacitor value would be around 20pF, and i could accept a rising time adding up to 4ns.

    Help designing a 10MHz square wave oscillator with very short Tr/Tf

    I want to generate a 10MHz square wave with Tr/Tf less than 2ns(or is this demand seems very odd? But it's really in need). The solutions all i could imagine now is: 1. use of a TCXO or the like, i checked several oscillator supplier's data sheet, the Tr/Tf is all around 10ns with a oscillating...
