I have a question regarding the design of a differential amplifier with an active load in cadence. My aim is to make it work with supply voltage 1V and current 10~20uA with STM065nm technology. I have problem swinging and getting the right values for the transistor widths. What should be my approach when designing the differential amplifier? Should I start swinging the differential pair or the active load transistor pair first? I managed to achieve a transfer function somehow close to the ideal, but still it is far from the normal one. You can find a screenshot of my schematic below.
