For High-Frequency Low-Current Second-Order Bandpass Active Filter Topology and Its Design in 28-nm FD-SOI CMOS , how to derive expressions (1c) and (1d) ?
1. For expression (1c) : Cgs2 and Cdb5 are not in parallel with Cgd5 and Cgd1 . Besides, how to obtain (1+ gm2/gm3)*Cgd2 ?
2. For expression (1d) : Cgd4 and Cgd6 are not in parallel with Cdb4, Cdb6 and Cbs1
I tried to replicate the cmos bandpass filter circuit, but it does not seem to work for now.
Anyone found any mistake in the circuit ?
