Novel DC-Offset Cancellation Techniques for Even-Harmonic Direct Conversion Receivers

Page 2554.

Abstract:

We present two novel dc-offset cancellation techniques for antiparallel diode pair even-harmonic mixers in a direct conversion receiver. Using fundamental equations, we describe the contribution of diode mismatch to dc offset and present an intrinsic mechanism of dc-offset cancellation. Similarly, we describe an extrinsic method of cancellation utilizing the second harmonic of the local oscillator. The cancellation techniques are successfully incorporated in fully monolithic C-band direct conversion receivers and mixers. Measurements confirm the equations and verify complete cancellation using the proposed methods. This works provides a solid foundation for the design and development of fully monolithic and high-performance direct conversion receivers.
