Abstract/Summary:
This dissertation investigates high frequency devices and circuit modules for biochemical microsystems. These modules are designed towards replacing external bulky laboratory instruments and integrating with biochemical microsystems to generate and analyze signals in frequency and time domain. The first is a charge pump circuit with modified triple well diodes, which is used as an on-chip power supply. The second is an on-chip pulse generation circuit to generate high voltage short pulses. It includes a pulse-forming-line (PFL) based pulse generation circuit, a Marx generator and a Blumlein generator. The third is a six-port circuit based on four quadrature hybrids with 2.0~6.0 GHz operating frequency tuning range for analyzing signals in frequency domain on-chip. The fourth is a high-speed sample-and-hold circuit (SHC) with a 13.3 Gs/s sampling rate and ~11.5 GHz input bandwidth for analyzing signals in time domain on-chip. The fifth is a novel electron spin resonance (ESR) spectroscopy with high-sensitivity and wide frequency tuning range.
