Abstract:
Aspects of a method and system for generating quadrature signals utilizing an on-chip transformer are provided. In this regard, a pair of phase-quadrature signals may be generated from a single-phase signal via a transformer, one or more variable capacitors, and one or more variable resistors integrated on-chip. The transformer may comprise a plurality of loops fabricated in a plurality of metal layers in the chip. Each of the one or more variable capacitors may comprise a configurable capacitor bank and each of the one or more variable resistors may comprise a configurable resistor bank. The one or more capacitor banks may be programmatically configured on-chip, based on a frequency of the single-phase signal. The one or more resistor banks may be programmatically configured on-chip, based on a frequency of said single-phase signal.
