Abstract
An integrated circuit (IC) includes a voltage-to-current converter circuit having a first voltage terminal, a second voltage terminal, a first current terminal, and a second current terminal. A transimpedance amplifier (TIA) and biquad filter circuit has a first TIA and biquad filter input coupled to the first current terminal and has a second TIA and biquad filter input coupled to the second current terminal. The transimpedance amplifier includes cross-coupled transistors configured to use positive feedback.
