The following equation needs to be solved in an application circuit using op-amps. Indicate the type of amplifier required along with the required voltage gain value. P = 6X - 9Y i. Amplifier 1: ii. Amplifier 2: iii. Amplifier 3: Gain = Gain = Gain =

A certain op-amp has two internal amplifier stages with the following gains and critical frequencies; Av1 = 50 dB, Av2 = 25 dB, fc1 = 1500 Hz, and fc2 = 3000 Hz. Determine the open loop midrange gain in decibels and total phase lag when f = fc1....

5 please all parts will give like!!!

Figure 6 (a) shows the circuit diagram for a differential amphfier. You may assume that M and M, have identical parameters. Referring to Figure 6 (a): (a) What kind of amplifier is it? What is its role in a three-stage op amp? Draw the small signal equivalent eircuit and derive the differential voltage gain Aag. For the analysis consider RDI RD2 >>Rp State any assumption. (b) RD. gml gm gm, and r re=r What is the new Adr in the circuit of Figure 6 (b), where a PMOS current source has replaced the two drain resistors Ror R Rp and a NMOS current sink has replaced the source resistor Rs? (c) What are the advantages in using the circuit of Figure 6 (b) instead of Figure 6 (a) to realize an op amp? (d) Ven Ms Mg Rp1 Rpa Vo HM, My M Ma M3 Vss 0 V Vss 0 V Figure 6(b) Figure 6 (a)
