Current mirrors as active loads for differential pairs, presentation about OTAs (link), Linearity of the differential pair in weak and strong inversion regions, mismatching and layout rules. Discussion of the first questions on an exercise dealing with sizing transistors in an OTA. Link to the OTA exercise, with handwritten solution. Recorded live April 22, 2017. If you are curious about the origin of the sqrt(WL) term when normalizing standard deviations for sigmas_beta and sigma_T, you can read this paper (around figs. 3 and 4, for example).
