WebMay 22, 2024 · The OTAs are designed using the simple symmetrical CMOS OTA structure shown in Fig. 2.5. To get a transconductance of 1.33 mA/V, the amplifier bias current is chosen as IB = 336 μA. The limits are specified as VS = 3.27 v, IS = 560 μA; the capacitances are determined as C1 = 100 pF, C2 = 50 pF. WebAug 17, 2016 · In the particular case of a symmetrical OTA, the second way of enhancing slew-rate maintaining a low static power consumption consists in dynamically changing the current mirror’s copy ratio as it is shown in Fig. 1. In these architectures, a 1:1 copy ratio is maintained at small input signal.
