Abstract
An integrated electron spin resonance (ESR) circuit chip includes a chip substrate, a transmitter circuit, and a receiver circuit. The transmitter circuit and receiver circuit are disposed on the chip substrate. The transmitter circuit includes an oscillator circuit configured to generate an oscillating output signal and a power amplifier (PA) circuit configured to generate an amplified oscillating output signal based on the oscillating output signal. The receiver circuit receives an ESR signal from an ESR probe. The receiver circuit includes a receiver amplifier circuit configured to generate an amplified ESR signal based on the received ESR signal, a mixer circuit configured to receive the amplified ESR signal and to down-convert the amplified ESR signal to a baseband signal, and a baseband amplifier circuit configured to generate an amplified baseband signal based on the baseband signal.
