摘要：

A new oscillating circuit is proposed to estimate resistance and parallel parasitic capacitance of chemical sensors. The circuit is able to reveal resistance in a wide range, from tens of k Omega to over than 100 G Omega. Experimental results of a discrete board prototype confirm the very good performance of post-layout simulation tests concerning the CMOS integrated implementation.
