Rparmay induce strange phase jumps around
ωcfor BS case when left with the default value; they are
360ojumps and using the "
phase unwrap" option will correct them. Default is set because the error log will otherwise complain about possible "
Matrix is singular" due to the G-sources directly driving a capacitor with no DC current path.
