Abstract
A solution for generating a clock using a quadrature delay can include a first plurality of in-phase (I) inverter pairs configured to output an I signal according to a first input and an inverted in-phase (inverted I) signal according to a second input, with a phase delay circuit coupled in parallel to each of the plurality of pairs. The solution can include a second plurality of quadrature (Q) inverter pairs configured to output a Q signal according to a third clock signal input and an inverted Q signal (inverted Q) according to a fourth clock signal input and a phase detector including a plurality of cells, each of which can receive at least one of the I signal, the inverted I signal, the Q signal or the inverted Q signal and include at least one or more transistors having a gate connected to a ground.
