Abstract
An apparatus is disclosed for a harmonic rejection filter with transimpedance amplifiers. In an example aspect, the apparatus includes a harmonic rejection filter with at least three input nodes, at least one output node, a first transimpedance amplifier, a first set of transimpedance amplifiers, and a scaling current converter. The at least three input nodes include a first input node, a second input node, and a third input node. The at least one output node includes a first output node. The first transimpedance amplifier is coupled between the first input node and the first output node. The first set of transimpedance amplifiers include a second transimpedance amplifier coupled to the second input node and a third transimpedance amplifier coupled to the third input node. The scaling current converter is coupled between outputs associated with the first set of transimpedance amplifiers and an input of the first transimpedance amplifier.
