What multiple of the time constant T gives the time taken by an initially uncharged capacitor in an RC series circuit to be charged to 80.6% of its final charge? Number Units
The figure shows five 5.53 Ω resistors. Find the equivalent resistance between points (a) F and H and (b) F and G. (Hint: For each pair of points, imagine that a battery is connected across the pair.) (a) Number Units (b) Number Units
The bridge configuration shown in the figure below contains 3 known capacitors: C1 = 11.4 nF, C2 = 82.8 nF, C3 = 29.1 μF, and unknown capacitor C4. The system is charged by battery V = 18.6 V. What is charge Q4 on the unknown capacitor, when the bridge is balanced (that is, the voltmeter shown in the figure reads zero)?: Q4 = μC
For the short-channel device shown in Figure 4, given that Vdd = 2.5 V, Vt0 = 0.4 V, γ = 0.1 V0.5, velocity saturation voltage V'DSAT = 1 V, |2ϕF| = 0.6 V. [15 pts] a) Determine the different modes of the device while Vo is changed from 0 to Vdd. [ 7 pts ] b) Derive the condition for Vo at the boundary of each operation mode and give the corresponding value of Vo. [8 pts ] Hint: Threshold voltage Vt = Vt0 + γ(2ϕF+VSB − 2ϕF). Figure 4.
