Hi all,
I am doing a project to design and simulate a transmission circuit. The core of the circuit if a Colpitts Oscillator and a FSK modulator. The osc frequency is 30 Mhz. I am reading abt Oscillator, many documents abt that. But FSK
very hard to find. I wanna get a simple circuit to start with. My question is Can we use CMOS transistors to make a FSK modulator(simple one), I saw on the net there are a lot of diagrams abt FSK but in block type, some using matlab to model FSK, some use PLLs..... I am very new with RF so got a lot of troubles at the beginning.
Any suggestions for me to start with this problem. Ah i am using Cadence SpectreRF to simulate.
Tks
