TY - GEN A1 - Killat, Dirk A1 - Pitonak, Pavol A1 - Ulmann, Bernd T1 - High-precision CMOS multiplier with wide dynamic range T2 - 2025 32nd IEEE International Conference on Electronics, Circuits and Systems (ICECS) N2 - Multipliers are an important general-purpose analog function. Precision multipliers are still mostly based on bipolar transistors. In CMOS, small-signal based multipliers are often used as mixers. There are many approaches in CMOS that use the squaring characteristics of the MOSFET, but they do not come close to the accuracy and linearity of bipolar multipliers. This paper presents a new principle and verifies it on a four-quadrant multiplier on a test chip in 65 nm CMOS technology. A new type of input predistortion is used to drive the cascaded differential stage. With a supply voltage of 1.2 V and differential input signals of up to ±700 mV, a linearity of better than 0.5 % of the measurement range is achieved over a wide temperature and frequency range.
