  • Abstract
    A fully balanced (FB) transconductor using two multi-input single-ended CMOS transconductors is proposed. The FB transconductor achieves a 2Vpp linear input range at 2.5 V power supply and consumes 1.74 mA. The output resistance of the FB transconductor is 2 MΩ. It operates at 2 V with linear input-range of 1.2 Vpp and at 1.6 V with linear input-range of 0.9 Vpp. A 2.5 V 2.5 MHz FB Gm-C filter using the FB transconductors achieves a CMRR of 45 dB and a passband IIP3 of 32 dBm
