Abstract: Guanella topology balun/unun impedance transformer contains cascaded, i.e., series-coupled, coils of different sizes implemented in RF CMOS technology. The cascading of differently-sized coils provides for a large resonance-free operating bandwidth. The shunt inductive loading maximizes low frequency performance.
