Hi,
I have a question about trapezoidal ringing.
I have a question about trapezoidal ringing.
During my oscillator simulation, a trapezoidal ringing has been found through spectre.out.
However, when I checked the problematic node reported, the shape of the ringing seems like an ADC output, a quantized analog waveform, not two point shape.
Would it be a right report ?
*** The problematic node is an internal node of a three terminal resistor of ~700 ohm.
(Plus/Minus terminal is connected to GND, and the other terminal a noisy VDD)
*** The peak to peak value of the ringing is around 20 uV.
Any advice would be appreciated.
