How to make sure QVCO output has accurate in-phase & quadrature phase clock? I use the parallel type QVCO (identical osc).
In my testbench A, the qvco works properly but when move to testbench B, it did not wok properly like: no longer 90o shift, different swing amplitude. It looks like it depends on initial voltage of the oscillator.
thank you in advance.
