Q. Explain Inductorless Filters
Inductorless (Active) Filters
Filters (used to pass or eliminate certain frequency components of a signal) that are suitable for IC fabrication, but which do not contain inductors, are known as active filters. They have the op amp as a common component. Figure 5.4.13 shows the basic op-amp circuit with frequency-dependent impedances. The voltage gain or voltage transfer function of this circuit is given by
with Zi = Ri and Zf = Rf (1/j ωCf ) (i.e., Rf and Cf in parallel). We have a low-pass filter with
is sketched in Figure 5.4.14, from which one can see that at the half-power or 3-dB point of fl, the dc value Rf /Ri goes down by a factor of 1/ √ 2 or 0.707. With Zf = Rf and Zi = Ri + 1/j ωCi (i.e., Ri and Ci in series), we have a high-pass filter for which we obtain
2 n -R D/A CONVERTER An n-bit 2 n -R D/A converter needs 2 n resistors of equal value R and (2 n+1 -2) analog switches. A 3-bit 2 n -R D/A converter is shown in Figure, which
in DC series generator we consider Eg=V+Ia(Ra+Rse).But in DC shunt generator why it is only Eg=V+IaRa and not Eg=V+Ia(Ra*Rsh/Ra+Rsh)
