Step 1 of 11 4.049P signal model and C, are short current source The modified R, + RD Figure Step 2 of 11 The dynamic resistance diode is voltage division rule Substitute = voltage (1) Substitute 25mV and (2) Step 3 of 11 current Thus from 0.9mA 1.1mA Equation diode current is equation voltage Here =1mA 0.9mA Step 4 of 11 The voltage =-2.634 mV The voltage 1.1mA The varies from -2.634 mV Diode across voltage formula the range Thus, 2.634mV (3) Step 7 of 11 Consider Substitute 0.5 for 0.5= 10x10' Substitute 0.5 for 2.634mV 2.383mV 0.5 5.268mV 4.766mV Step 8 0f 11 Consider the is 0.10 Substitute 0.10 for 0.1 =0.0225mA Substitute 2.634mV 2.383mV 0.1 0.1 -26.34mV Step 9 of 11 Consider gain is 0.01 Substitute 0.01 =0.2475mA Substitute 2.634mV 2.383mV 0.01 0.01 263.4mV 238.3mV Step 10 of 11 Consider voltage gain Substitute 0.001 for 10x10 Substitute 0.01 for 2.634mV 2.383mV 0.001 2383mV Step 11 of 11 Therefore current lowing through the current and input voltage range different gains are shown in Table 1 (mA) (mV) 0.5 0.0025 -5.268 766 0.1 0.0225 -26.34 23.83 0.01 0.2475 -263.4 238.3 0.001 2.4975 -2634 2383 Therefore current flowing through the current source input voltage range different gains are
