Abstract
A voltage-controlled oscillator (VCO) includes a power supply node configured to have a power supply voltage. A reference node is configured to have a reference voltage. A transformer-coupled band-pass filter (BPF) is coupled to a pair of transistors. The pair of transistors and the transformer-coupled band-pass filter are positioned between the power supply node and the reference node.
