Summary: We describe A 3 GHz sensor for SCM with sub-zeptofarad sensitivity. The sensor is based on the designs of Tran et al. PCB Prototype is being used as a test bed and the first step towards a single-chip SiGe BiCMOS SCM presently being developed at the James Watt Nanofabrication Centre (JWNC) of the University of Glasgow.
