Create the layout design for MOS NAND3 gate using a depletion-type transistor with VTL = -0.3V and enhancement-type transistors with VTO = 0.5V such that VOL is less than or equal to 0.1V. VDD = 2.5V , tox = 10nm and 2X = 0.6μm .
A telecommunication system has a link bandwidth of 10 MHZ, signal propagation of 3.5 x 10^8 m/s, transmitting as 1500 frames per minute, with 15000 bits per frame, over a distance of 100 km. What is the bandwidth-delay product?
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
Design a passive first-order RC low-pass filter with a cutoff frequency fH = 10 kHz. Derive the step response and voltage transfer function.
A gaseous mixture containing 50 mol% hydrogen and 50 mol% acetaldehyde (C2H4O) is initially contained in a rigid container at a total pressure of 760 mmHg absolute. The formation of ethanol occurs according to C2H4O + H2 C2H6O.
