ASK demodulator Design

[shaikss]

Hi,

I am designing a ASK demodulator.
Can you pls tell me how to give ASK modulated signal in Cadence ADE L?
I don't want to design ASK modulator and give that signal as input to demodulator. With the available instances Vsin/Vsource, how can I give a modulated signal to demodulator as input?

Use 2 square-wave Vsources with different frequencies and switch them alternately via 2 switches to the ASK input. Control the 2 switches via a 3^rd square-wave Vsource with either a fix frequency, or use a VPWL source (perhaps controlled by a VPWL file) to achieve irregular switching timing.
