| Abstract(in English) | The circuit structure having two cross-coupled,emitter-coupled pairs is proposed as a fundamental analog function element to multiply two electrical input quantities;the input voltage difference and the tail current difference.The simplest form is well-known as a ″Gilbert multiplier cell″.In this circuitry,the t ail current difference is the differential output current of an emitter-coupled pair,nearly proportional to the differential input voltage.If the tail current difference is the differential output current of a squaring circuit,nearly proportional to the square of the differential input voltage,a squaring multiplier is obtained and is applied for radio communication application as a frequency mixer with a local oscilator frequency doubler.Furthermore,if the tail current difference is the differential output current of a multiplier,a tripler which can multiply three electrical input quantities is obtained. Furthermore,the folded technique for low voltage operation and the multitanh technique for its input voltage range expansion are discussed. |
