چکیده

A new architecture of simple low voltage BiCMOS fourquadrant multiplier is proposed and analyzed. It operates with ±1.5V power supplies and 3Vp-p fully input signal swings. Simulation results based on AMS 0.8μm n-well BiCMOS process parameters are given to verify the theoretical analysis. The architecture of four multipliers typically have a nonlinearity error less than 1% over ±1.5V input range and a −3dB bandwidth of several GHz. The total harmonic distortion for frequencies up to 4GHz is less than 6% with maximum input voltage at ±1.5V. Simple structure, low-voltage and low power capability, and high performance make the proposed multiplier quite feasible in many GHz nonlinear signal processing applications.

Symmetric ultralow-voltage floating-gate rail to rail four quadrant analog multiplier

The floating-gate transistor can be used to design analog circuits, such as current mirrors [1], current scaler[2] and current multiplier [3, 4] and divider [4]. The multiple input floating-gate transistor can be used to design ultra lowvoltage “pseudo differential” pairs [1], hence ULV rail-to-rail amplifiers and analog multipliers are feasible using the floating-gate technique. In this paper ...
