Find the equation for change in frequency of VCO?
(a) △fo = (2×△Vc)/(RT×CT×Vcc)
(b) △fo = △Vc/(4×RT×CT×Vcc)
(c) △fo = △Vc/(2×RT×CT×Vcc)
(d) △fo = (4×△Vc)/(RT×CT×Vcc)
I had been asked this question during an interview.
This question is from Voltage Controlled Oscillator topic in portion Phase Locked Loops of Linear Integrated Circuits
