Enter the email address you signed up with and we'll email you a reset link. and only the cosine term is used. NOTE: Ewald scales as O(N3/2) and is thus extremely slow for This velocity saturation phenomenon is one of a host of issues that occur in short-channel devices, resulting in iD increasing more slowly with vGS than predicted by the square-law relationship. modulo the last value, i.e. (a) Find the value of RE to establish a de emitter current of about 0.5 mA. These amplifiers are therefore known as capacitively coupled amplifiers. As a safety measure, test the good working condition of this circuit by applying a low voltage supply like 24V AC or 12 V AC with a small load like a low wattage bulb. For your design, how far is the drain voltage from the edge of saturation?
