Question

In a 4 -bit weighted resistor DAC, the resistor value corresponding to LSB is 8 k$\Omega$. The resistor value corresponding to MSB will be

• A. 2k$\Omega$
• B. 1k$\Omega$.
• C. 4k$\Omega$.
• D. 0.5k$\Omega$

Answer 1

The correct option is B 1k$\Omega$.

(b)
MSB resistance = $\frac{8k\Omega }{2^{4-1}}=\frac{8}{8}=1k\Omega$
