STA Problems to calculate setup time and hold time and maximum operating or clock frequency or minimum Time Period required. Before starting to read this article try to understand the basics of static timing analysis (STA) such as, 1. What is Static Timing Analysis (STA)? 2. Why Static Timing Analysis (STA)? 3. Where we use STA Static Timing Analysis? 4. What is setup time and how to avoid setup time violations? 5. What is hold time and how to avoid hold time violations? 6. How to calculate the maximum clock frequency fmax or minimum time period Tmin required for the given sequential circuit. Setup time (Tsetup_time) Well Setup time in STA
Synchronizers and Metastability in Digital Logic Circuits CMOS Interview Questions by VLSI Universe - May 5, 2020July 21, 20210 The circuits which accept the input that can change at arbitrary times and produces output with a nonzero probability of Metastability are Synchronizers. The sequential logic elements are mainly characterized by the setup and hold times. If the input data changes before the setup time the output reflects a different new value after a bounded delay. If the input data changes after the hold time the output reflects a different old value after a bounded delay. and If the input data changes between the setup and hold time constraint or aperture then the output may be unpredictable and irrelevant. That is the output may go to a metastable state. Now let us analyze how a Latch will respond to a voltage that will change

Important Interview Analog Circuits Answers Analog Interview Questions by VLSI Universe - May 2, 2020July 21, 20210 The section contains analog circuits questions and answers on Resistor networks, transistor MOSFET, current mirror, Opamp, and RC circuits (transient analysis). Answer 1. Answer 2. If RC >> T, then the circuit acts as an integrator. If RC << T, Here the time constant is very small, so the capacitor will be charged very fast and the output voltage almost follows the input voltage. Answer 3. Given a DAC circuit so the value 1010 corresponds to the 10 in decimal and it is 4-bit. Therefore the least significant bit will be equaled to Vred/16 = 8/16 = 0.5V. Hence the value 1010 is 0.5*10 = 5V. One more method by using a superposition theorem also it can be solved. Answer 4. Vthe = 400mV. The
