Abstract (in Japanese) (See Japanese page) 
(in English) High speed Gm-C filter requires high speed and high linearity Gm-cell like a flipped voltage follower; however it has poor input dynamic range.
This issue can be resolved by a level shifter, but it suffers peaking at high frequency.
To reduce peaking, a compensation technique using a capacitance is investigated.
The capacitance is inserted in parallel with the level shifter to pass frequencies exceeding the bandwidth of the level shifter.
This suppresses the influence of the level shifter on the frequency response of the circuit, so that the peaking is decreased.
According to the simulation results, the peaking is reduced from 3dB to 0.25dB by inserting 500,fF capacitance and the bandwidth achieves about 30,GHz.
