This thesis provides a theoretical and experimental study of injection locking and reconfigurable charge-domain sampling mixers and filters for data communications over wireless channels. On injection-locking, the intrinsic relation between the characteristics of injection signals such as sinusoidal or square, single-tone or multi-tone, the type of oscillators under injection such as harmonic oscillators (passive or active LC oscillators) or non-harmonic oscillators (ring or relaxation oscillators), and the lock range of the oscillators under injection was investigated. For the very first time, we discovered the intrinsic relation between the lock range and the phase of multiple injections of harmonic oscillators. In addition, we obtained the closed-form expression of the lock range of harmonic oscillators with square-wave injections. Moreover, we obtained the distinct characteristics of the lock range of harmonic and non-harmonic oscillators and that of different types of non-harmonic oscillators. These theoretical findings were not known before and were validated using simulation results. On reconfigurable charge-domain sampling mixers and filters for software-defined radio, a novel quadrature charge-domain down-conversion sampling mixer with embedded finite-impulse-response (FIR), infinite-impulse-response (IIR), and 4-path bandpass filters was developed. An in-depth investigation of the principles of periodic impulse sampling, periodic windowed sampling, and periodic N-path windowed sampling was presented and a detailed mathematical treatment of charge-domain windowed samplers with built-in sinc, FIR and IIR filters was provided. The proposed quadrature charge-domain sampler with embedded FIR, IIR, and 4-path band-pass filters was implemented in IBM 130 nm 1.2V CMOS technology and its performance was validated both using simulation results and on-wafer measurement.

“…Charge-domain sampling (CDS) that provides sinc-type lowpass filtering and finite impulse response (FIR) filtering via a multiphase integration is another effective technique for programmable channel selection while providing adequate suppression of aliasing interference. The attenuation for blockers and aliasing signals provided by CDS, however, is inadequate for most wireless standards [3][4][5]. It is highly desirable to incorporate high-order sinc-type filters in charge-domain samplers to increase the stopband attenuation while preserving frequency selectivity, aliasing interference suppression and low power consumption.…”

A charge-domain downconversion sampling mixer with an embedded four-path bandpass filter for band selection and a sinc 3 finite impulse response (FIR) and a first-order sinc FIR with a decimation of 4 for channel selection is proposed to provide sufficient attenuation of outof-band blockers and aliasing interferences. The sampling mixer designed in an IBM 130 nm 1.2 V CMOS with a 100 MHz input exhibits an 80 dB suppression of aliasing interferences and a 57 dB stopband attenuation while consuming 1.08 mA.
