Switched inverter - A new technique for sample data low-voltage and low-power applications

In this paper, a new technique called 'switched inverter' for analog sample data signal processing is proposed. The circuit is based on the conventional CMOS inverter operating as a transconductor. The proposed circuit does not require linear capacitors and employs switches that operate at fixed channel voltage. Owing to the use of inverters, the proposed structure presents class-AB operation. A 8'th taps FIR filter has been designed in a standard 0.35-μm CMOS technology at 0.6 V supply.
