Low-noise amplifier for homodyne radar receiver in vehicle, has N non-inverting operational amplifiers with output and input of amplifier connected to outputs and positive inputs of operational amplifiers, respectively
The amplifier (10) has N non-inverting operational amplifiers (1 1 to 1 N) connected in parallel. The input (E) of the amplifier is connected to positive inputs of the operational amplifiers. The output (S) of the amplifier is connected to outputs of the operational amplifiers. Negative inputs of operational amplifiers are connected to a mid-point of a potential divider formed by two resistances (R1 1, R2 1). The first resistance of potential divider is connected to reference potential, and the second resistance is connected to output of the amplifier.
