Active-RC biquad is proposed, which allows the DC level of the input of operational amplifier (op-amp) to be different from that of the op-amp output, enabling the low-voltage operation. The proposed biquad realizes a second-order transfer function with only one op-amp, rendering even lower power consumption. By cascading two biquads, a 0.6 V fourth-order filter is realized in a 0.13 mu m CMOS technology. While dissipating only 0.42mW, the filter shows 2.11 MHz cut-off frequency and 62dB spurious-free dynamic range. Copyright (C) 2008 John Wiley & Sons, Ltd. |
