Abstract:
A circuit for a low-power and blocker-tolerant mixer-amplifier stage may include a complementary mixer formed by transmission gates having complementary structures. The complementary mixer may be configured to receive one or more radio-frequency (RF) signals and to convert the one or more RF signals to intermediate frequency (IF) current signals. A complementary TIA may be coupled to the complementary mixer and may be configured to receive the IF current signals and provide IF voltage signals. The complementary TIA may be formed by coupling an NMOS-TIA and a PMOS-TIA to a common load. A first portion of the complementary mixer may be coupled to the NMOS-TIA and a second portion of the complementary mixer may be coupled to the PMOS-TIA.
