1 ECE2c Problem set #4: Problem 1: The MOSFET has a +0.3 Volt threshold voltage and g ox sat W C v =0.5 mA/V (assume velocity-limited characteristics, i.e. ) 1 )( ( ds th gs g ox sat d V V V W C v I ) , where we will assume =0.25 1 V . If the device is biased with 1 Volts Vds and Vgs=0.5 Volts, find the transconductance and output conductance. Problem 2: The MOSFET has a +0.3 Volt threshold voltage and g ox sat W C v =0.5 mA/V (assume velocity-limited characteristics, i.e. ) 1 )( ( ds th gs g ox sat d V V V W C v I ) , where we will assume =0.25 1 V . If the device is biased with 1 Volts Vds and 0.25 mA drain current, find the transconductance and output conductance Problem 3: We will now consider a mobility- limited FET, ie. ) 1 ( ) )( 2 / ( 2 ds th gs g g ox d V V V L W C I where ) 2 / ( g g ox L W C =1 2 V / mA and =0.25 1 V . If the device is biased with 1.5 Volts Vds and 0.25 mA drain current, find the transconductance and output conductance Problem 4: A bipolar transistor has = 50 and A V =100 V. If the device is biased with 1.5
