An output pad contains a chain successively large inverters to drive the (relatively) enormous off-chip capacitance. If the first inverter in the chain has an input capacitance of 20fF and the off chip load is 10 pF, how many inverters should be used to drive the load with the least delay? Estimate the delay, expressed in F04 inverter delays?
Implementation of the project with the analog and digital modulation techniques
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Design a single state amplifier that satisfies the following specifications. State the transistor used and show all equations. 1. The voltage gain is greater than or equal to 0.9 and less than or equal to 1.0 2. The source resistance is 10k ohms
A pn-junction is uniformly doped and has dopant concentration of NA = 4 x10^16 cm-3 in the p-region at 300K. AT zero bias, 20% of the total space charge region (W) is extended in the p-region. Calculate Vbi, ND, W, xn and xp.
Three balanced three-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400+j300 Ohms per phase;[ load 2 is delta-connected with an impedance of 2400-1800j Ohms per phase; and load 3 is 172.8+j2203.2 kVA.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
A car travels at 30 km/hour. The diameter of the tire is 50 cm. Giving consideration to the Nyquist frequency how many shots of the tire must be taken to correctly capture the motion of the wheels
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
