Latest Patents

One of his latest patents is a highly efficient constant transconductance power amplifier. This invention discloses a highly efficient constant transconductance power amplifier that includes a positive error amplifier, a negative error amplifier, four current sources, two differential current controllers, and a constant gm biasing circuit. The amplifiers utilize deliberate offset voltages to create two transconductance amplifiers that operate in the appropriate cycle. The positive current sources provide current outputs, while the negative current sources sink the current. The differential current controllers manage the current flow to the load, which is proportional to the differential input signal. The constant transconductance biasing circuit ensures stable biasing voltage, eliminating drift associated with process variation. This invention results in improved performance, low power consumption, lower operating voltage, increased dynamic range, and stable processing characteristics.

Another significant patent by Kuo is an electro-optic apparatus and method for measuring the electric-field vector. This invention measures a two-dimensional electric-field vector by focusing two linearly polarized laser beams on different bottom planes of an electro-optic crystal. The reflected beams from these planes travel different paths within the crystal, resulting in different phase retardation when an electric field is applied. The electric-field direction can be calculated using two differential signals proportional to the phase retardation of the reflected beams.
