If g is the transconductance, r is the resistance due to channel length modulation and if only M3 and M2 has channel length modulation, what is the total voltage gain? |
| A. | R/ g * {(1 + gr)* R + R} || R * R / {(1/g || r) + R |
| B. | R/ (1/g) * g * {(1 + gr)* R + R} || R * {(1/g || r) + R |
| C. | R/ (1/g + R) * g * {(1 + gr)* R + R} || R * R / {(1/g || r) + 3R |
| D. | {(R || 1/g || r) / (1/g + (R || 1/g || r)} * g * [{(1 + gr)* (R || 1/g || r) + (R || 1/g || r)} ||R] * R / {(1/g || r) + R |
