Translinear sinusoidal frequency tripler
Electronics Letters, 2002 By direct synthesis of a trigonometric identity, this circuit generates an output signal frequency that is three times the input signal frequency. Frequency-doubling with free 90° phase shifter is embedded in the same circuitry. Simulation results demonstrate the functionality and the performance of the circuit.
