Patent ID: 7292092

Claim:
A resonator circuit, the circuit having a first phase stage comprised of: a first inverting transconductor ( 110 ) having an input and an output; a first non-inverting transconductor ( 120 ) having an input coupled to the output of the first inverting transconductor ( 110 ) to form a first circuit node (I) and an output coupled to the input of the first inverting transconductor ( 110 ) to form a second circuit node (Q); a second inverting transconductor ( 112 ) having an input and an output, where both the input and output are coupled to the first circuit node (I); a first capacitor ( 114 ) coupled to the first circuit node (I); a third inverting transconductor ( 122 ) having an input and an output, where both the input and output are coupled to the second circuit node (Q); and a second capacitor ( 124 ) coupled to the second circuit node; where the first inverting transconductor ( 110 ), the first capacitor ( 114 ) and the second inverting transconductor ( 112 ) are fabricated on a die substantially symmetrically to the first non-inverting transconductor ( 120 ), the second capacitor ( 124 ) and the third inverting transconductor ( 122 ) along an axis (A) of the die.
