The counter in a ring oscillator based ADC
counts freq_signal x pulse_width_ref or time_period_ref x freq_signal. Now if the counter is 10 bits I am wondering if their ratio should be 1024 for 10 bit resolution. If freq_signal=3khz and freq_ref=4khz, how do i make them work?
Shall i use divide by N counters to reduce one make the ratio....or is it done by counting multiple times till the counter is full?
