Correction to: Analog Integrated Circuits and Signal Processing  https://doi.org/10.1007/s10470-019-01501-2

Unfortunately, in the original version of the article some typos occurred. The typos have been corrected with this erratum. Below are the corrections:
  1. (1)

    Table 1 contains 2 repeated figures. There should be just the first two horizontal figures and then the equation cell.

     
  2. (2)

    In Eq. 6, the first matrix row contains the term: \( a - \left( {r_{e} + \frac{1}{{g_{m} }} + \frac{{r_{e} }}{{g_{m} r_{0} }}} \right) \), which is wrong. The right term is without a, and should be \( - \,\left( {r_{e} + \frac{1}{{g_{m} }} + \frac{{r_{e} }}{{g_{m} r_{0} }}} \right) \).

     
  3. (3)

    In Table 4, the first term in the first equation should be \( C_{1} C_{2} L \omega^{{\left( {\alpha + \beta } \right)}} { \sin }\left( {\frac{{\left( {\beta + 2\alpha } \right)\pi }}{2}} \right) \) by making \( \left( {\alpha + \beta } \right) \) the power of \( \omega \).

     
  4. (4)

    In Sect. 7, the simulated frequency is 86.25 kHz not 86.25 Hz.
