The TOCA based integrators provide better high frequency properties and require less capacitance compared with their counterparts which use conventional operational amplifiers. A sixth-order band-pass ladder filter with centre frequency 455 kHz, 0-5 dB ripple, and 80kHz bandwidth is simulated. A third-order electronically tunable low-pass ladder filter with 0-3 dB ripple and a biquad filter with low-pass and band-pass outputs are experimentally demonstrated using TOCAs which are realized with discrete components. The techniques will be useful for monolithic integration in the analogue filtering circuits. © 1991 Taylor & Francis, Ltd. |
