Hey all:
I have a question on the LDO load transient (P-Pass LDO, internally compensated). According to most of the literature, the voltage undershoot/overshoot with a fast load transient can be calculated as V=(I/(C*BW)), where I is the load variation, C the output buffer capacitance and BW...
Hey thylacine1975:
Thank you very much for the answer. You are absolutely right in this application, the reactance seen by the PA can vary significantly and mostly due to the different coupling coefficient and loading. But I found some paper that makes a "robust" class E by means of transductor...
Hi:
I need to design a PA driving an IMD working at 13.56MHz. But due to the weak coupling between the TX and RX coil, the equivalent load impedance(including all ESRs) ends up around 6 Ohm. According to equation Vdd=(Rl*Pout/0.577)^0.5, the supply voltage is calculated to be only 500mV. Is my...
