  • #10-a
    current sensitivity and (b) voltage sensitivity of M2 and M1.
    Ans : Current sensitivity of M1 is given as:



    And, current sensitivity of M2 is given as:



    Ratio



    Hence, the ratio of current sensitivity of M2 to M1 is 1.4.
    (b) Voltage sensitivity for M2 is given as:



    And, voltage sensitivity for M1 is given as:

    ``V_{s1}=\frac{N_1B_1A_1}{K_1R_1}``

    Ratio

    ``\frac{V_{s2}}{V_{s1}=\frac{N_2B_2A_2K_1R_1}{K_2R_2N_1B_1A_1}``

    Hence, the ratio of voltage sensitivity of M2 to M1 is 1.
  • #10-b
    voltage sensitivity of M2 and M1.
    Ans : Voltage sensitivity for M2 is given as:



    And, voltage sensitivity for M1 is given as:

    ``V_{s1}=\frac{N_1B_1A_1}{K_1R_1}``

    Ratio

    ``\frac{V_{s2}}{V_{s1}=\frac{N_2B_2A_2K_1R_1}{K_2R_2N_1B_1A_1}``

    Hence, the ratio of voltage sensitivity of M2 to M1 is 1.
