| + | Due to lack of corelations between instances on test bench, it is not possible to check above parameters in the standard AC simulations on replica circuits. \\ | ||
| + | The solution is to run MC on //stb// analysis and use following expressions to obtain histograms of DC open loop gain, phase margin and gain-bandwidth product: \\ | ||
