  • Abstract
    An accurately tunable, low-voltage, linear continuous-time filter is presented in this paper. The system, designed using 0.18 μm CMOS process, occupies 0.4 mm2 of area. The filter part of the circuit dissipates 2.6 mW and the tuning part of the circuit dissipates 2 mW of power. The filter achieves good tuning accuracy. The THD of the filter for a 10-kHz, 250-mVpp signal at 0.8-V supply voltage is 0.01%.
