摘要：

Some new MOSFET-C integrators and CMOS current conveyors for realisations of the ladder filters are proposed. These integrators require smaller capacitance than with those currently used. The integrators also provide a better high-frequency performance in terms of gain and phase error responses. A sixth-order bandpass ladder filter, with 460 KHz centre frequency, 0.5 dB ripple, and ripple bandwidth 120 KHz, is designed and simulated. A third-order lowpass filter, with 2 dB ripple and 50 KHz ripple bandwidth, is experimentally demonstrated. The results reported in the paper will be useful in the realisation of high-frequency integrated continuous-time filters.
