2. Consider a CE-amplifier as shown below. Given Vcc = 1.8 V and power dissipation under large signal bias, P = 1 mW. Assume VBE 0.8 V and V, = 0.025 v. (a) Find Ic and mi (b) What is the value of Re that would result in maximum output voltage range; (c) Find Aye from part (b). Voc = 1.8 V Rc Vin
A PV array with terminal voltage around 48 V under standard conditions is connected to a step-up dc-dc converter to supply a load at 120 V, 5 A. The input inductance is 8 mH with an internal resistance of 0.2 ohms, and the switching frequency is 5 kHz. Assuming ideal circuit components, calculate the duty ratio (k) and average input current (I1). Evaluate the maximum peak-to-peak input current ripple for the converter. If this current is limited to 2% of...

Download the datasheet for 2N3904 and find the value of Bp. (Hint: Use average value) Be= Voc +10 V RB We are going to consider the common emitter configuration circuit shown in the figure to test a 2N3904 npn Bipolar Junction Transistor (BJT) under DC bias conditions. Your circuit should place a fixed collector resistor, Rc, in the circuit to prevent the collector current, Ic, from exceeding 40 mA (for this, you know that the minimum value of is zero)....
