The authors describe the negative impedance converter, a simple analog building block which can be readily implemented in CMOS. They present a circuit based on the inverse-function approach, providing precise temperature-compensated linear operation. Applications include single-pin crystal oscillators, zero-impedance current sensing, and wideband integration. Simulated and measured characteristics are in good agreement, and show that useful negative resistance can be obtained to over 10 MHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
