Step of 4 10.092P Consider a current mirror loaded MOS differential amplifier. The differentia amplifier is biased with mA and all resistors are identical. The early voltage, Calculate the value of V = (0.2mA) The two NMOS transistors of the differential pair operating at the over drive voltage = 0.2 V. The two PMOS transistors of the differential pair operating at the over drive voltage = 0.2 V. All transconductances are identical. Calculate the value of 2ID 8m = V Step of 4 Write the formula for the low frequency differential gain. Substitute the corresponding value. = Therefore, the DC value of the voltage gain is, 50 Step of 4 Write the expression for the pole frequency. 1 Here, The output resistance is, = Calculate the value of = 50 kΩ The total capacitance at the output node of the mirror is 0.2 pF Substitute the corresponding values. = = 15.9 MHz Therefore, the frequency of the first pole is, 15.9 MHz Step of 4 The total capacitance at the input node of the mirror is 0.1 pF Write the expression for the pole frequency. Substitute the corresponding values. = 1.6 GHz Therefore, the frequency of the second pole is, 1.6 GHz 1.6 GHz Write the expression for zero frequency. Substitute the corresponding values. = 3.2 GHz Therefore, the frequency of the pole is, 3.2 GHz
