The given figure shows a self-biased transistor amplifier using a Si transistor with VCC = 20 V, hFE

The given figure shows a self-biased transistor amplifier using a Si transistor with VCC = 20 V, hFE = 400 and VBE = 0.65 V. The transistor should be biased at VCE = 10 V and IC = 0.6 mA. Find the value of RC; RE, R1 and R2 such that it meets the following specification over the temperature range 25–145 °C. DIC DIC 10  ; VBE at 25  C ¼ 650   50 mA, ICO at 25 C ¼ 5 nA max; Ico at 145  ¼ 3: mA max Assume that percentage change in IC due to VBE and ICO is same (5%).
