I able to get a phase of 50. I wanted to know if there is any way of pushing the non dominant pole further away so that my UGB and phase margin improves. Please suggest some texts which I could refer. Thanks

Reduce the power or reduce the size of input pair to reduce GBW=gm/CL 2. Reduce the length of cascoded device or increase the size of cascoded devices, which equivalently increase the gm of cascoded devices.
